ME3600-ME3800: service-instance & bridge-domain syntax
Hello,
what is the best practice for the configuration of L3VPN on Cisco ME3XXX ?
Old Syntax:
interface GigabitEthernet0/1
switchport trunk allowed vlan none
switchport mode trunk
service instance 2 ethernet
encapsulation dot1q 3
rewrite ingress tag pop 1 symmetric
bridge-domain 4
interface vlan 4
vrf forwarding L3VPN-1
ip address 2.2.2.1 255.255.255.0
New Syntax:
interface GigabitEthernet0/1
switchport trunk allowed vlan none
switchport mode trunk
service instance 2 ethernet
encapsulation dot1q 3
rewrite ingress tag pop 1 symmetric
bridge-domain 4
member GigabitEthernet0/1 service-instance 2
interface vlan 4
vrf forwarding L3VPN-1
ip address 2.2.2.1 255.255.255.0
The new syntax is very much similar to the new syntax for L2VPN, see:
http://www.cisco.com/en/US/docs/switches/metro/me3600x_3800x/software/design/guide/ME3600x_Design_Guide.pdf
I'm soon sending in the field some more ME3600, so I'd like to start right.
Best Regards
Andrea
Hello.
You might have confused service instance configuration and usual switchport mode trunk.
Please refer figure 11-10 in the document http://www.cisco.com/c/en/us/td/docs/switches/metro/me3600x_3800x/software/release/12-2_52_ey/configuration/guide/3800x3600xscg/swevc.html
>But there is a typo - per description it should be "enc doat1q 20" under service instance 9on the picture).
Also under Figure 11-2 we have following example:
QinQ is also supported when sending packets between an EFP and a switchport trunk, because the switchport trunk is implicitly defined as rewrite ingress tag pop 1 symmetric. The same external behavior as Method 1 can be achieved with this configuration:
Switch (config)# interface gigabitethernet0/1
Switch (config-if)# service instance 1 Ethernet
Switch (config-if-srv)# encapsulation dot1q 1-100
Switch (config-if-srv)# bridge-domain 30
Switch (config)# interface gigabitethernet0/2
Switch (config-if)# switchport mode trunk
Again, service instance 1 on Gigabit Ethernet port 0/1 is configured with the VLAN encapsulations used by the customer: C-VLANs 1-100. These are forwarded on bridge-domain 30. The service provider facing port is configured as a trunk port. The trunk port implicitly pushes a tag matching the bridge-domain that the packet is forwarded on (in this case S-VLAN 30).

Bridge-domain and trunk configuration on ES20 card.
Hello.
I have two 7609-S boxes equipped with ESM20G cards and WS-X6748-GE-TX cards. A trunk is configured on ports of WS cards between these devices. A very important system is to be connected with two optical links to both devices via ES20 cards for redundancy. I consider configuring it using EVC framework in the following way:
service instance -> bridge-domain XXX -> interface VLAN XXX and enable HSRP on my devices.
I am not sure what is the structure of conecting system so I would like to have some kind of L2 connectivity between my devices for this connection. For other connections made using ports on WS card a dedicated VLAN is allocated for every one of them and then this VLAN is simply put in trunk between devices. Can I simply add vlan XXX to the list of VLANs allowed on the WS-card-based-trunk or do I have to utilize some completely different solution? Links to any related documentation are appreciated. Tomorrow I am going to test this configruation any way but I would like to have some backup solution in case this will not work.
Thanks in advance,
Andrew.Hi Andrei,
Im having the same dilemna and im wondering if you were able to find a solution for this?
I need to support HSRP on a vlan interface with bridging over port channel bundled interface between routers.
im trying this but i cant seem to get this to work.

ME3600 does not forward frames out one interface in service instance
Hi,
I have an issue with ME3600 running 15.3(1)S. I have a BDI used for CPE
management.
cisco ME-3600X-24FS-M
Cisco IOS Software, ME360x Software (ME360x-UNIVERSALK9-M), Version
15.3(1)S, RELEASE SOFTWARE (fc1)
This is the BDI and VRF configuration:
interface Vlan1620
ip vrf forwarding 65000:1620
ip address 10.232.28.1 255.255.252.0
no ip redirects
ip vrf 65000:1620
rd 65000:1620
route-target export 65000:1620
route-target import 65000:1620
address-family ipv4 vrf 65000:1620
redistribute connected
The MPLS part is working fine, no issues there. There is also a DHCP
pool handing out IPs to the CPEs.
ip dhcp pool 65000:1620
vrf 65000:1620
network 10.232.28.0 255.255.252.0
domain-name xyz
default-router 10.232.28.1
option 66 ascii 10.232.28.1
dns-server 8.8.8.8
lease 0 0 30
This also works fine and I have verified that CPE has both IP and GW.
Then for the service instance configuration:
interface GigabitEthernet0/5
switchport trunk allowed vlan none
switchport mode trunk
service instance 1620 ethernet
encapsulation dot1q 1620
rewrite ingress tag pop 1 symmetric
bridge-domain 1620
interface GigabitEthernet0/11
switchport trunk allowed vlan none
switchport mode trunk
service instance 1620 ethernet
encapsulation dot1q 1620
rewrite ingress tag pop 1 symmetric
bridge-domain 1620
Traffic to CPEs behind Gi0/11 works:

It does work to ping locally from the 3600 though:

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.232.28.190, timeout is 2 seconds:
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
I'm not sure how to troubleshoot it further. I've also tried setting up
ERSPAN sessions for RX traffic on Gi0/5 but I don't get anything in
unless I ping 28.1 which is the IP of the interface on the 3600.
Any clues?

Now that you can buy a firewire HD and Firewire cards (check out driver chip type first)without breaking the bank, this would be the simplest option for a RAC.

ME3600 - SVI's + Service Instances
Hi Everyone,
Very new to the ME3600 platform, so hoping someone can assist with the following:
We currently have 4948's connecting to various carriers - Each port is a trunk, and has a vlan per tail.
i.e.
int gig1/1
desc AGG_TO_CARRIER_A
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk allowed vlan 10,20,30
We then have another port on the 4948's (Trunk), that allows all vlans from all the carrier AGG ports that connects to 7200's or ASR1000's (We have multiple POP's), and each vlan is then added to dot1q subint and thrown into a vrf or standard "Inet" Interface....we also apply service-policys (egress shaping/ingress marking) on the L3 Interfaces
We are wanting to run MPLS on the ME3600s, and do all the L3 stuff on them rather than the 7200'sand ASR's - So, we will still have the 4948's, multiple carrier AGG's, multiple vlans's but the trunk port(From the 4948s) that currently goes to the 7200's and ASR's will now go to the ME3600s - So, a few questions:
1. What would the ME3600 Trunk port(That connects back to the 4948) config look like? i.e. Similar to how we currently do it (switchport trunk allowed vlan 10,20.30,40...), and then create SVI's for each vlan and apply L3/VRF/service policies? Or do SVI's not support service policies and we would need to use service instances? (The 4948's typically have ~100+ vlans(tails) from the various carrriers)
2. If service instances are required, can anyone please provide an example of how the config would look (Or point me to some documentation please?)
Thanks in advance for your help.Ariean wrote:
1.) Thanks for your reply, so load balancing and/or fail over will only happen between different instances of the single database or can it also be possible between 2 different databases provided the databases are in sync??
Yes, it can be done between two databases as well and this is called Standby database configuration. This won't do the load balancing for you but you would get teh switchover (or Failover) between two.
2.) Would it be possible to have PROD & DR database servers with load/fail over options configured and also with dataguard setup between those 2 DB's will have same IP addresses & host names like below?
PROD DataBase Server tsjipud186.xyz.mq.abcd.net 123.45.67.30

Hi,
Im Currently using a 4431 router configuring it with a bridge domain. Im encountering problems with the bridge domain interface not able to ping my load balancer IP address.
We have one 4431 router connected to 2 2960 switches with 2 F5 connected to both of the switches also.
Below is my configuration for the bridge domain:
interface BDI1
ip address 192.168.1.219 255.255.255.224

Im not able to ping my load balancer IP address:

Has anyone encountered this before?
Below is the network diagram:
Thanks,
MarvinDid you do a no shut on the BDI?
"The initial administrative state of a BDI depends on how the BDI is created. When a BDI is created at boot time in the startup configuration, the default administrative state for the BDI will be up, and will remain in this state unless the startup configuration includes the shutdown command. This behavior is consistent with all the other interfaces. When a BDI is created dynamically by a user at command prompt, the default administrative state is down." -
ME 3800 X - QinQ across service instance
I realize a test rig of ME-3800-X.
I use the MPLS and QinQ.
EoMPLS for pseudowire is Ok in test rig.
QinQ also.
In fact, everything is ok.
But, in documentation, it is not said that we can forward the frame QinQ across a Service Instance.
Header:vlan+eth+data >>ingress 3800 -A >> evc bridge-domain 100 >>>>>> Vlan 100 and rewite imposition and Xconnect to B>>
egress 3800 -A >> Eompls+QinQ+Vlan+eth+data >>>>
|
|
BACKBONE MPLS
|
|
>>>ingress 3800- B >>>> Vlan 100 (not rewite) + xconnect to A >>>> evc bridge-domain 100 >>>>egress 3800 - B > Header QinQ+ETH+DATA
It has QinQ frames within the bridge domaine not frame Vlan.
Question:
Is what I can do this even if the documentation does not indicate.
Thanks for your comment.
I am french, sorry for my bad english language.
Cdlt,Hello Cdlt.
but what is the question? Is it something like "how come that even if my configuration does not match the guide my setup is working?"
Is that one?
Also, does it work when your config is matching the EVC guide instead (the one in green on your pdf)?
Quick notation is that even if the configuration is not matching the guide the final result is the same as you moved the pop operation of the outmost dot1q tag from the ingress PE (the one on top) to egress one by configuring 'platform rewrite imposition tag push 1 symmetric' on the SVIs.
So you either strip the qinq tag on ingress or on egress the frame looks like the same way when the last mpls label is popped.
Does this answer to your question or am I still missing the point?

Q-in-Q on an EVC/Service Instance
Hi
I want to take a bunch of VLANs from an interface, trunk them through my network, and spit them out on another end. Sounds like simple Q-in-Q to me.
Problem is one end is a 3600X, and the other is a 4900M. The 4900M is simple. The problem I have is with the 3600X and the EVC. Let's say I want to take VLAN 10 from a customer, and carry it on my network as VLAN 100. I will take them from a port on my 3600X and then carry VLAN 100 along with another bunch of unrelated VLANs through my network.
Can I configure a service instance on the customer facing port encapsulating their VLANs (let's say VLAN 10 for this example), then carry the internal VLAN (100) through on my trunks?
Example, 3600X:
interface GigabitEthernet0/1
description FACING CUSTOMER NETWORK
switchport trunk allowed vlan none
switchport mode trunk
service instance 1 ethernet
encapsulation dot1q 10
bridge-domain 100
interface GigabitEthernet0/2
description FACING SERVICE PROVIDER CLOUD
switchport trunk allowed vlan 100
switchport mode trunk
Then the 4900M will be:
interface GigabitEthernet0/1
description FACING CUSTOMER NETWORK
switchport access vlan 100
switchport mode dot1q-tunnel
interface GigabitEthernet0/2
description FACING SERVICE PROVIDER CLOUD
switchport trunk allowed vlan 100
switchport mode trunk
This doesn't work. I've tried various configs on the 3600 but can't get it working. I am not sure how to config the EVC properly - on the 3600X I suspect I also have to configure a service instance on the trunk facing into the cloud? This unfortunately isn't preferable as I want this to function as a basic, normal trunk (it has about 50 other VLANs on it).
Cheers for any help!Not sure in 4900M, I would have to test it, but in ME switch, I believe you would have to push a tag because it seems you don't care about which VLAN it comes in.
So for example, your encapsulation would be anything.
service instance 1 ethernet
encapsulation dot1q 1 - 4094
rewrite ingress tag push dot1q 100 symmetric
This would push a second VLAN (100) in a tagged frame that reaches the port.
The symmetric would pop it when sending out of that interface so the inner VLAN would be kept. -

please explain me, where tags would be pushed/popped and why??
thank you.Hello.
You might have confused service instance configuration and usual switchport mode trunk.
Please refer figure 11-10 in the document http://www.cisco.com/c/en/us/td/docs/switches/metro/me3600x_3800x/software/release/12-2_52_ey/configuration/guide/3800x3600xscg/swevc.html
>But there is a typo - per description it should be "enc doat1q 20" under service instance 9on the picture).
Also under Figure 11-2 we have following example:
QinQ is also supported when sending packets between an EFP and a switchport trunk, because the switchport trunk is implicitly defined as rewrite ingress tag pop 1 symmetric. The same external behavior as Method 1 can be achieved with this configuration:
Switch (config)# interface gigabitethernet0/1
Switch (config-if)# service instance 1 Ethernet
Switch (config-if-srv)# encapsulation dot1q 1-100
Switch (config-if-srv)# bridge-domain 30
Switch (config)# interface gigabitethernet0/2
Switch (config-if)# switchport mode trunk
Again, service instance 1 on Gigabit Ethernet port 0/1 is configured with the VLAN encapsulations used by the customer: C-VLANs 1-100. These are forwarded on bridge-domain 30. The service provider facing port is configured as a trunk port. The trunk port implicitly pushes a tag matching the bridge-domain that the packet is forwarded on (in this case S-VLAN 30). -
Hi everybody.
At work , I have seen a lot of bridge domains configured on a single switch. My question is what is bridge domain and why we use them. An example with configurations will be great.
Thanks and have a great day.Hi Marvin and Rick
Please consider the following config and questions:
R1# show platform
Interrupt Throttling:
Throttle Count = 00052552 Timer Count = 00039372
Netint usec = 00000800 Netint Mask usec = 00000240
Active = 0 Configured = 1
Longest IRQ(usec)= 00003999
MSFC CPU IDPROM:
IDPROM image:
(FRU is 'C7600 MSFC4 Daughterboard')
+++++++++++++++++++++++++++++++++++++++++
R1#show running-config interface gigabitEthernet 9/7
service instance 1251 ethernet
encapsulation dot1q 1251
rewrite ingress tacg pop 1 symmetri
bridge-domain 440
service instance 2001 ethernet
encapsulation dot1q 2001
rewrite ingress tag pop 1 symmetric
bridge-domain 440
+++++++++++++++++++++++++++++++++++++++++
Let say R1 receives a packet with vlan tag 1251 on g9/7. What will happen next? will R1 update its MAc table with source mac?
1)Will there be a mac table for bridge -domain 440? Do we have one-to one correspondence between the two i.e each bridge-domain has its own mac table.?
2)Let say R1 receives a packet with vlan tag 1251 on g9/7. What will happen next? will R1 update its MAc table with source mac?
3) Let say R1 receives a frame with vlan tag 1251 with destination mac ff:ff:ff:ff
What will R1 do next?
4)Will R1 forward it to all service instance in bridge-domain 440 except the one R1 receives the broadcast frame?
( in our case we have two service instances under bridge -domain 440 i.e service instance 1251 ethernet,service instance 2001 ethernet)
5) Will R1 change the vlan tag 1251 to 2001 when forwarding the broadcast frame out of instance 2001?
Appreciate your help.

Hi.
I would like to know is there a command to see traffic througput over service instance?
Thank youHello.
You might have confused service instance configuration and usual switchport mode trunk.
Please refer figure 11-10 in the document http://www.cisco.com/c/en/us/td/docs/switches/metro/me3600x_3800x/software/release/12-2_52_ey/configuration/guide/3800x3600xscg/swevc.html
>But there is a typo - per description it should be "enc doat1q 20" under service instance 9on the picture).
Also under Figure 11-2 we have following example:
QinQ is also supported when sending packets between an EFP and a switchport trunk, because the switchport trunk is implicitly defined as rewrite ingress tag pop 1 symmetric. The same external behavior as Method 1 can be achieved with this configuration:
Switch (config)# interface gigabitethernet0/1
Switch (config-if)# service instance 1 Ethernet
Switch (config-if-srv)# encapsulation dot1q 1-100
Switch (config-if-srv)# bridge-domain 30
Switch (config)# interface gigabitethernet0/2
Switch (config-if)# switchport mode trunk
Again, service instance 1 on Gigabit Ethernet port 0/1 is configured with the VLAN encapsulations used by the customer: C-VLANs 1-100. These are forwarded on bridge-domain 30. The service provider facing port is configured as a trunk port. The trunk port implicitly pushes a tag matching the bridge-domain that the packet is forwarded on (in this case S-VLAN 30). -
VPLS: bridge-domain o xconnect?
Hi all,
to attach an interface to a vfi I have seen two kind of possible solution:
L2 vfi <name> manual
Vpn id <VPNid>
bridge-domain <bridge-domain id>
Neighbor <Remote-PE>
interface fastethernetx/y
bridge-domain < bridge-domain id>
or
interface fastethernetx/y
xconnect vfi <name>
What is the difference between the command bridge-domain o xconnect? When I must use one or the other?
Thanks in advance
Gianlucahi! I am not entirely sure about it but this is my best shot...
X-connect would be used to establish a pseudo-wire (point-to-point) for an EPL service like EoMPLS. That will just connect the 2 UNI together to the VC created by the X-connect command. In this case ther would be no mac table maintained for the VSI in the router.
Bridge domain can be used so that you create a seperate bridge domain ( like a virtual bridge) and add ports to that and connect it to remote PE so that you create a VPLS connection. The PE will maintain a seperate mac table for the VSI.
So thats what I think - PWE3 v/s VPLS..
Correct me if I am wrong.
Thanks.... -
Bridge Domain and multicast traffic
Hi All,
i am planning to build a Point to multipoint network based on ME3600X switch at the HQ and ISR 2900 routers at the Branches. i need to simulate a lan service.
i though of using EOMPLS at the ISR 2900 and closing them at the ME3600X. at the ME3600X i will use bridge domain to have this point to multipoint functionality.
at the configuration guide i saw that when i am using bridge domain i need to disable IGMP snooping on every Vlan.
my question is how the bridge domain treat Multicast traffic ?
furthermore, can i mix EOMPLS and Bridge Domain ?
Thanks,
Avi.Hi Avi,
ME3600X doesn't support VPLS yet (check with your account team for the roadmap) so I don't think your design will work here. What you can do is having a router behind the ME3600X which will have a dedicated VLAN with each remote site.

Hi guys,
Couldn't really get into logic of bridge-domain and hsrp coexistence. How traffic will be flooded?
Imagine following topology:
Bridge-domain and hsrp is running between ASR1 and ASR2.
Host C has two network adapters. Both are in UP state, but only one of them is forwarding traffic.
I am curious, what path traffic will take from host A to host C and from B to C in situation when :
1) net.adapter #1 is active
2) net.adapter #2 is active
p.s. active router for hsrp remains the same.
We have captured traffic on the devices, and it was a bit confusing to me that standby hsrp router was forwarding traffic from host B out of g0/0/0/0 and pw 3
I would appriciate any help...Okay, that really make sence. Thank You very much for the explanation!
Yes, You are right, that's RNC.
Theoretically the MAC address should be flushed away from the memory when the switchover of the network card appears, because, the connection for some seconds goes down.
Could You please tak a look on the following output:
As I understand, both ASR's do know where 0040.4384.8260 (This is RNC NPGEP mac address) is. So basically there should not be any flooding..
