3750 as MPLS PE !!!
Hi,
I came across this link "http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps5532/product_data_sheet0900aecd806e27b9.html"
It says that 3750 can be used as an L2/L3 PE... for me it sounds too good to be true.
Am I missing something... is anyone here using these to provide MPLS based L2/L3 services.
Please suggest.
Thanks
Cheers

It's weird because I browse the 3750 Metro configuration guide and it seems that you can run bgp process on it (with vpnv4 address so MP-BGP)
http://www.cisco.com/en/US/docs/switches/metro/catalyst3750m/software/release/12.2_44_se/configuration/guide/swmpls.html#wp1021082
It's confirmed in this picture too : http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps5532/images/product_data_sheet0900aecd806e27b9-3.jpg
So it should be possible to use 3750M as a PE, i'm very interested by this solution for our metropolitan network !

3750 - ME - MPLS P(E), Stackwise, EoMPLS
Hello,
I've three questions:
- can I use Cat 3750-ME with Advanced IP licence as MPLS "P" device, or is it "PE only" device - which feature is missing?
- 3750-ME has StackWise port, but it isn't supported now. Is there any chance it will be supported at least for "LAN features".
- 3750-ME Configuration Guide states:
"You cannot have a direct Layer 2 connection between PE routers with EoMPLS". I haven't found such limitation mentioned in Cat 6500 documentation. Is this limitaion only for Cat 3750-ME platform, or is it general limitation of this feature, independent on hardware ?
Thanks
Jan Klicka1. yes its functionality really is a PE but it can label switch also. Think about how these devices are usually deployed (ring format). That means they need to do limited P switching but as Paul Daniels would say "not a lot".
2. Sorry havent a scooby doo.
3. I really dont get that statement - I would need to ask "why not?". -
Hi all,
Do anyone know if it's possible to run MPLS over a 100BaseFX SFP in the ES port of a Cisco Catalyst 3750 Metro Edition?
BR
/DanielOk, Just wanted to reduce the confusion.
1) MPLS support : YES.
Its part of the software. And the IOS for 3750 supports MPLS to be configured on ES ports, with more QOS and other functions as well.
2) 100 BASE SFP Support - YES.
Now you have a question clubbed in for hardware support of 100BASE SFP on 3750. What ever SFP you put in ES ports MPLS will run. Now for support of hardware question.
Yes 100BaseSFP is supported in 3750 series Gigabit SFP uplinks.
Here is the link:
http://www.cisco.com/en/US/products/hw/modules/ps5455/products_data_sheet0900aecd801ba88e.html
Although you are not at all utilizing the 3750 to the fullest by using a 100BASE SFP but again it depends on your requirement.
But the support is there. :-)

Is it possible to connect a CE via vrf to a PE (ISP) running full MPLS?
I believe the support for MPLS is there for 3750-Metro range. If you have a Cat 3750 then MPLS is not supported.
But you can although configure MultiVRF CE as described in an earlier post in this thread.
You can run a layer 2 trunk to your next-hop Full MPLS PE and, create dot1q subinterfaces on both sides for the required number of VRF's. There shouldnt be any performance issues as far as i know with this setup.
In fact not carrying your IBGP to your aggregation edges (CE's) you have a leaner network, which is the way to go for enterprises trying to virtualize their network.
Here is a reference link for configuration sample.

URGENT: MPLS P/ PE support on 7600/Sup720-BXL and 3750 Metro switch
I'm need to design a MPLS network for a Cable Operator.
They will start small with some Cisco CMTS doing MPLS-PE and needing only two devices to aggregate these PE and delivering Services (Internet connection, VoD, ...) , so they will need to work has P/PE.
For that I want to know if it's possible to:
1 - Use 3750 Metro and 7600/Sup720-BXL as P and PE
2 - Who many customers (L2VPN/VLANs and/or L3VPN/VRF) can they support?
Searching in CCO I found these values/features but, need URGENT to check:
1 - sup720-bxl supports P and PE but 3750 only PE?
2 - 3750 supports 1024 VLANs and 8,192 MPLS labels but no values on L3VPN/VRF?
SUP720 supports more than 1000 VRF?
Really need urgent HELP on this design/capabilities for these two devices.
Thanks in advance,
MP
Network Consultant - CCIEbefore you even get anywhere close to the numbers of L2/L3 on a 7200 I would seriously consider asking what throughput you can get through a 7200 with MPLS, QOS, L3vpns and L2vpns configured. I have done this testing already but dont think it is appropriate to quote the figures publically.

MPLS Configuration Problem- Catalyst 3750
We have a difficulty enabling the MPLS on this particular switch. We couldn't find the command for the MPLS to enable in the interface. Is there any command or substitute command to do this? The following information was taken from the switch.
Device details:

System image file is "flash:c3750-ipservices-mz.122-25.SEE2/c3750-ipservices-mz.122-25.SEE2.bin"
cisco WS-C3750-24P (PowerPC405) processor (revision K0) with 118784K/12280K bytes of memory.If I understand I don't need to configure trunk in physical interface:
The correct configuration is:

switchport trunk encapsulation dot1q
switchport mode trunk
interface GigabitEthernet1/0/1

Does BT IP Clear MPLS support multicast?
Hi
Requirement is to multicast music on hold RTP stream from a Data Center to a remote site over BT IP Clear MPLS network. Catalyst 3750 switches (both running IP Services Image) will BGP peer with BT PE equipment. The Catalyst 3750 switches will also be configured with PIM-SM.
Does BT MPLS support IP Multicast? I could not find any info on the web so I am hoping people have tried it and (hopefully) it worked for them!
Are there any restictictions/limitations using Catalyst 3750 for BGP peering?
Thankssidhu
If you are looking for multicast support on mpls link then you need to ask your SP to provide you the mVPN services. Because they need to configure the default and data mdt under the vrf.

Hi all. We are in the midst of rolling out Mpls to 5 of our remote sites. 3 sites will have a cir of 10 mbps, 1 100mbps, and another 250 mbps. I am planning on running ospf in each site. My question is, will a 2821 router at each site be sufficient. Voice and data will be in use, so traffic shaping/qos will need to take place on these routers. Will this work. Thanks for your help.
Ah, you didn't mention you were using Metro Ethernet connections. 3750 will easily handle 100 or 250 Mbps.
As for tips for QoS, insure your voice is sent first. All data could be placed in a normal class or you could split it, with the 3 remaining classes, into critical, normal and scavenger if using non ES ports. Doubtful you need to do much more if using one of the ES ports, although it would be nice if you could do FQ in class default like you can on WAN routers but don't believe you can.

MPLS Customer Edge always necessary?
Hello,
As I wrote in a previous discussion, I'm planning to deploy a MPLS network with VPN capabilities.
My question is, is it really necessary to have a router on every client?? Does it has to be a specific router?
What features does a customer edge needs to work with MPLS VPNs?
If I use a 3750 Metro can I avoid the need for a router on the customer edge? I'm thinking about enabling EoMPLS on the customer ports, connecting the customers to that ports and then establish the MPLS link using the enhanced services ports.
Thanks in advance for your help.Hi,
MPLS now a days is used frequently by pre-sales guys to impress clients, like we will give you a MPLS connection, etc.
However from clients or CE perspective MPLS is nothing more then a leased line.
So, it doesn't matter if your CE is router or PC or any other thing, as far as it is capable of send traffic to the PE.
All the label switching and also VPN forwarding is done on PE.
Kindly let me know if you have any queries.

Comparison between 3750 and 3750-metro
hi folks,
is there any links which will provide me on the comparison between 3750 and 3750-metro? for exapmple, isis is not support on 3750 but it support on 3750-metro. The product information from cisco site is insufficient in term of the main differences :p

josh.wHi Josh,
The Cisco Catalyst 3750 Metro Series is built for Metro Ethernet access in a customer location, enabling the delivery of more differentiated Metro Ethernet services. These switches feature bidirectional hierarchical QoS and Traffic Shaping, intelligent 802.1Q tunneling with class-of-service (CoS) mutation, VLAN translation, MPLS, EoMPLS, and Hierarchical Virtual Private LAN Service (H-VPLS) support, and redundant AC or DC power. They are ideal for service providers seeking to deliver profitable business services, such as Layer 2, Layer 3, and MPLS VPNs, in a variety of bandwidths and with different SLAs.
The metro switches have the PXF chips (which allow hierarchical QoS on the 2 "WAN" GigE ports, so several logical links can share a connection, and have soft bandwidth limits).
For more details on 3750-M switches have a look at this link

Hello, I work for a small service provider that wants to offer its users MPLS and MPLS-VPN.
What considerations should I consider for deploying MPLS?
For examples i see that MPLS is configured on physical interfaces, but our network design have all virtual interfaces, I should consider or take into account the configuration?
I've also read that it is important the value of MTU, what is the proper value?
we have the following equipment: Cisco 3750 metro, Cisco 7606, Cisco catalyst 3500XL switch, Cisco Ubr7246, Cisco 1800 router.
Much appreciate your considerations.
thanksSandip Thanks for responding.
If you add 12 bytes to the MTU, this would be for each label and each prefix?
So if I have 50 prefixes would be 12 bytes x 50 total for the MTU?
Currently I have configured a cisco 3750 metro against a cisco 7606, my question is regarding the MTU on the cisco 3750, this is correct MTU value?
On 7606
interface Vlan472
mtu 1530
ip address ....
ip ospf network point-to-point
mpls ip
vlan 472
mtu 1530
interface GigabitEthernet2/10
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 472,703,715
switchport mode trunk
mtu 9216 (mtu one that can be set)
On 3750 metro
interface Vlan472
ip address ....
ip ospf network point-to-point
mpls ip
vlan 472
mtu 1530
interface GigabitEthernet1/1/1
switchport trunk allowed vlan 472,703,715
switchport mode trunk
System MTU size is 1530 bytes
System Jumbo MTU size is 9000 bytes
System Alternate MTU size is 1530 bytes
Routing MTU size is 1500 bytes
on the other hand, i not sure what the requirements for cisco equipment that perform the function of PE or P, that equipment is suitable for these functions and what IOS?

EoMPLS with Catalyst 3750 Metro Switches
Hi,
I am trying to setup an EoMPLS tunnel (VLAN mode) between two 3750 Metro switches. But I am not getting the Status down from the both PEs.Also the 'show mpls l2transport binding' shows no output interface and no label stack is attached. Can anybody in the forum help me out? Is it any IOS related problem.
The IOS version is:c3750me-i5k91-mz.122-25.SEG1.bin
Thank you,

I'm baffled why these vlans aren't showing on my 2811. Any ideas?
Thanks,
MikeHey All,
Thanks for the input! I was actually able to solve the issue. It appears that "sh vlans" is different on an IOS router than an IOS switch. On the router it shows sub-interface ISL/dot1q trunks to a switch. This is obviously different for me as I have a switching card. In order to see VTP in action on the router and verify it was working I actually needed to view it through the VLAN database. See below:
MPLS-TEST#vlan database
MPLS-TEST(vlan)#show
