Cisco huawei mpls l2vpn
Hi All,
While i m doing for the remote ldp formation between this devices of cisco 3600 & huawei 5700,
attached the configs of these 2 nodes.what could be the possible reason for this..

Administration of ASA5520 and cisco router mpls 1900
Hi
i just want to administor cisco
ASA5520 and cisco router mpls 1900
can some tell me as admin what to check as u get into office /reguraly in cisco asa 5520 and vpn mpls router for administrator ,right now its working as configured by supplier for remote sites to connect HQ and access several server
My interest to know what are the basic day to day checkup on cisco asa5520 working as ips and cisco asa 5520 working as content filtering and cisco vpn mpls
thx ,attached pic for ur view
JHello Malai,
This question is subjective, I mean you can check the statistics on the CSC module for logs of the users going to blacklisted sites.
You can check the CPU for the ASA's and IPS.
You can monitor the amount of traffic traversing the interfaces of the ASA, you can determine witch host is using most of the bandwith,etc.
Its pretty basic administration stuff

Hi,
I want to capture packet on gi0/0 of PE1 in order to show customer that all his traffic is encapsulated and transmitted by L2VPN (ldp signaling) in his lab.
CE1-----------(g0/1)PE1(g0/0)------------PE2-----------CE2
PE1 and PE2 are Cisco3945 and L2VPN is working well. I tried cisco RITE(Router IP Traffic Export Packet Capture) feature, but the output was not what I expected. I tried both export mode and capture mode. Only LDP hello message I got, looks like RITE is only interested in IP packet. Monitor session wasn't effective as well because it is not a switch.
Is there any other way/workaround to capture customer's traffic encapsulated in L2VPN?
What I did on PE1 when I was trying RITE export mode:
ip traffic-export profile test
bidirectional
interface GigabitEthernet0/2
mac-address e411.5b44.3a6d
interface GigabitEthernet0/2
ip address 10.1.2.1 255.255.255.0
interface GigabitEthernet0/0
ip traffic-export apply test
Gi0/2 connected my PC(10.1.2.2) with wireshark installed.
Many thanks.
Regards,
Jerry FanThanks Shivlu. I tried, but failed. 'monitor capture' is only interested in ipv4 and ipv6. Maybe the IOS in Cisco3945 isn't same as the IOS in Cat6500 or Cisco7600 or GSR/CSR.

At last, I have to insert a switch in the middle of two cisco3945 and configured port span. That worked very well. Anyway, many thanks for your advice.

Cisco 7600 MPLS and set Qos group
Hi, i'm am trying to use to following class-maps and policy maps on a Cisco 7600. The same maps have been used on both 3700 series and 7200 series. However when i try to apply IP_TO_MPLS_OUT and MPLS_TO_IP_IN on the 7600 (with SUP32 and 48 port gigabit blade) i get a message on the console
"set qos group" not supported.
I used the QoS group to carry the MPLS EXP value (as label would is popped) and this works well.
How can i get the QoS group to work on the 7600, if not is there a valid workaround?
Many thanks for your help.

I'm not aware that you can use qos groups on c7600 (LAN ports ?).
For the MPLS_TO_IP direction you can use 'mpls propagate-cos' on the egress interface as workaround. This rewrites the egress IP ToS with the internal DSCP (which is inferred from the topmost MPLS label).
For the IP_TO_MPLS direction you could just match on the original DSCP ?

Hi,
I am going to setup MPLS between some Cisco routers, switchs and Juniper routers. Is there anything need to pay attention to?
Thanks!Hi Harold Ritter,
As a part of your conversation. I would like to clarify one doubt. As my knowledge I know if we want to enable MPLS
in Cisco routers we should enable CEF first. Because then it can create adjaceny table and FIB and based on FIB it can create LFIB. My doubt is how about the same in other vendor routers( eg:Alcatel, Juniper). How those routers creates LFIB and eanble on routers. What all routing table structures they(other vendors)use to fuction MPLS and which table is equivalent of adjaceny table .I expect your precious reply for the same.
Thanks, -
Hi All,
Please explain me the difference betwreen AToM,VPLS,L2TPV3 and Pseudowire and routed Pseudowire.
Thanks in advance
Thanks,
Arun MohanHello Arun,
A pseudowire is a point-to-point bearer service capable of carrying Layer2 frames across a network between two defined endpoints. A pseudowire can be likened to a direct point-to-point connection between two endpoints - these endpoints consider themselves to be directly interconnected, even though in reality, there is a service provider that interconnects them.
There are various technologies that can be used to provide pseudowire services. One of them is the Any Transport over MPLS, or more recently, the Pseudo Wire Emulation End to End (PWE3), that uses MPLS labeling to create a label switched path over the provider that will carry the frames between two defined endpoints. AToM an PWE3 depend on MPLS being present and run in the service provider's network. Another technology used to provide pseudowire service is the L2TP protocol which is basically a protocol that encapsulates (tunnels) Layer2 frames into new IP packets that are routed over the service provider's network to the endpoints where they are decapsulated and the tunneled Layer2 frames are forwarded further. L2TP is a pure IP-based solution.
Frankly, I do not know what a routed pseudowire is. I haven't heard that term before.
All pseudowire technologies described so far emulate only a point-to-point direct connection. If more than two locations have to be interconnected, more pseudowires are needed. In general, if a full direct connectivity between N locations is necessary, you need to create N*(N-1)/2 pseudowires which is clearly not a scalable approach. Often, however, customers have many locations and request a kind of "Ethernet-alike" connection between them that behaves simply like an Ethernet switch that interconnects all these locations together, allowing immediate direct connectivity between these locations. The pseudowire as a point-to-point service clearly does not fit in here.
This is where Virtual Private LAN Service comes in. The VPLS allows you to interconnect multiple customer locations using an MPLS-based service provider network that emulates an Ethernet switch interconnecting all customer's locations. Apart from allowing all locations to communicate directly to each other, VPLS also takes care of replicating unknown unicast, multicast and broadcast traffic coming from a particular location to all other customer's locations, like a normal Ethernet switch would. VPLS network itself is based on routers running IP and MPLS and all operations are performed over MPLS label switched paths.
Best regards,

Troubleshooting of MPLS VPN 2 Network
I am at service provider. A user complains on Link down issue for MPLS L2VPN Link. And i log-in to user connected PE router and run the below mentioned command.
sh mpls l2transport vc 3407
Local intf Local circuit Dest address VC ID Status
Gi0/2.3407 Eth VLAN 3407 202.148.199.106 3407 UP
Guide me in analysing the output and further troubleshooting. Define the parameters observed for o\p of a command.Hi,
The P routers do not need VRFs or VPN labels because they are only transporting the packets towards the PEs. They do this by looking at the IGP label. This label is advertised by LDP. This is sometimes referred to as BGP free core. Although you will often have BGP running for other purposes on the P router.

hi,
can anyone explain the difference between, l2vpn and VLL.
regards,
jackBroadly MPLS L2VPN are categorized in to two different model Virtual Pseudo Wire Service (VPWS) & Virtual Private LAN service (VPLS). VPLS has last mile Ethernet drop at the customer premises. VPLS helps to extend your LAN domain to remote end via service provides WAN.

Hi,
Does cisco support mpls over atm-ppp-llc
per RFC 2354(PPP over AAL5).
Something like a scenario if Cisco acts as a PE and it gets frames with mpls over atm-ppp-llc from a connected CE ,is it supported in cisco , or it will drop the frames ?
Running mpls over ce-pe link is mandatory for the specific scenario.
Thanks
Thanks in advanceHello,
The MPLS should be supported also on PPP over AAL5. Simply use the "mpls ip" command on the Virtual-Template or the Dialer interface you are using on top of the ATM VC to set up the PPP interface.
The 3640 with proper IOS can support the PE functions. The Enterprise feature sets should be equipped with all features necessary to provide a PE router functionality - basically, the VRF, MPLS, LDP, MPLS VPN support, BGP, BGP VPNv4 support, IGP protocols with VRF support and that should be sufficient.
Best regards,

Job Requirements - MPLS experience
I'm a CCNP and have decent experience in the industry, however I have not worked for a service provider and do not have direct MPLS experience - only the education required for the CCNP tests. My understanding of MPLS is that it is a service provider technology that allows that provider to securely, quickly and efficiently provide virtual networks for their clients which will allow internal addressing to span the provider network, even if multiple clients use the same internal addressing. The end clients only use their standard routing protocols across the provider network and do not need to know anything about MPLS since it is transparent to them. Lately I’ve been seeing a few whitepapers that talk about using MPLS within large campus environments but I would be a bit surprised to see this used a lot because of the size of the campus that be able to gain the benefits of using it. (am I wrong?)
What I’m seeing lately though is that there are a lot of job advertisements that are looking for MPLS experience and are not talking to you unless you have it. In your opinion are they looking for 1) a former service provider engineer, 2) a person who worked for a client who used MPLS and although they won’t directly implement it they want someone familiar with it to support their traffic going across the MPLS, 3) someone to locally implement MPLS (and therefore my supposition from above IS wrong) or 4) they are looking for someone to continue to ‘bull’ them and tell them that they have experience when they don’t really have it?
I’m looking for opinions regarding the job economy out there. I know that you can’t know for sure what they are looking for unless you’ve placed the ad yourself. Please feel free to educate me as well if I’m making wrong assumptions. Thanks.actually, i could suggest cutting up your network and using bgp (ibgp not ebgp (unless you use a confed). the igp would be there to support ibgp. ibgp carries your IPv4 'customer' routing as it gives good control of ipv4 routing information flow (using tools like communities). this leaves the igp free to just support the infrastructure.
if you then throw mpls into the mix, it allows you to run multiprotocol bgp on top of the igp and ipv4 bgp. it also facilitates easy layer 2 circuits over your ip infrastructure (atom eompls), and engineer how those circuits work (mpls-te). mp-bgp also allows you to run mpls layer 3 vpn's (address-family vpnv4), which you could use as an alternative vlan technologies. when you are dealing with vlans, it is probably more difficult to control routing info flow between vlans - you need private vlans, acls etc, and you also need to extend this layer 2 across your network, introducing stp into the backbone. basically, i think managing l2 networks is more of a headache than managing l3 networks
with mpls layer 3 vpn, you can use overlapping vpns to achieve similar results to vlans, but without the l2 headache. it also allows you to easily run centralized services such as DHCP/NAT, provide multicast services inside mpls vpns, and provide internet access methods as well.
if you then think that you can provide ipv6 over an ipv4 network (without migrating to ospfv3 or isis or running 6to4 tunnels) using mp-bgp cisco 6pe, it makes it an attractive method of migrating to ipv6 without disrupting your core.
get hold of a book and read about overlapping vpns... cisco press mpls vpn architectures. you will then see the benefits of this over some enterprise type technologies. -
Transparent layer 2 tunneling through EoMPLS on Nexus 7K
Hello,
Does anyone know if the N7K supports transparent layer 2 tunneling of control traffic (CDP, STP and VTP) over EoMPLS? I'm unable to find exact info about this in Cisco's documentation.
Here's the problem I'm having:
I have an EoMPLS virtual connect configured between a ME3600X switch and a Nexus 7K switch to extend layer 2 domain across two different sites. The virtual connect is up and running and passing traffic successfully between the CEs. However, I'm having problem with tunneling CDP traffic from the N7K end to the ME3600X end. CDP tunneling in the other way is working fine. i.e. CE1 connected to the N7K is able to see the other CE (CE2) in its CDP table; however, CE2 connected to the ME3600X is unable to see CE1 in its CDP table, which I believe is caused by the N7K not tunneling the CDP traffic through the EoMPLS VC properly.
Below is the config:
! CE1 is connected to N7K port e3/28.
! CE2 is connected to ME3600X port g0/24.
! N7K:

I have this issue resolved.
There were reported bugs in earlier version of code for the ME3600X which dropped MSTP and RSTP BPDU's.
Also there are 2 different use cases for using the L2protocol command:
1, When creating a service instance between 2 devices that supports the L2protocol command use L2protocol tunnel (ME3600 to ME3600)
2, When creating a service instance between a deice that supports the L2protcol command and another device that does not support the L2protocol command use L2protocol forward (ME3600 - 2911 or ME3600 to non Cisco device)
I upgraded the s/w on the ME3600 to 15.3-2

Prefix FEC advertised over targeted LDP session
I am doing MPLS L2VPN interop testing with foundry XMR, IOS establishes the targeted LDP session with XMR fine and VC FECs are exchanged. However, I noticed that IOS is also advertising prefix-FEC mappings to XMR. This is puzzling me, since there is no directly link between Cisco and XMR, LDP does not have a link neighborship between Cisco and XMR, why would IOS advertise prefix-FEC? IOS should know that the lables it advertises are never going to be used by a targeted peer. The targeted LDP session is meant for VC-FEC mapping exchange only.
XMR only advertises VC-FEC over this targeted LDP session unless link-hello is also heard from its peer, in which case, both prefix-fec and VC-fec are advertisedJian,
This is the default behavior indeed and shouldn't cause any issue beyond the extra labels installed in the LIB.
You can easily change that behavior if you desire so by applying label filtering as follow:
no mpls ldp advertise-labels
mpls ldp advertise-labels for 1 to 2
access-list 1 permit any
access-list 2 deny
access-list 2 permit any
Hope this helps,
