How to configure VPLS L2VPN Pseudo Wire with MPLS


Hello, I'm needing some help setting up a layer 2 vpn between two X460-24t across a wan. I have all the necessary licensing and feature packs installed. The wan used static routing and is 3 hops away, also the routers in between do not participate in the MPLS. I've started setting up the MPLS and VPLS here's where I'm at...What am I doing wrong?

Matt,

Is the MPLS LDP session between the two VPLS endpoints in the operational state? The command to view the LDP sessions is "show mpls ldp peer". Also, which software version are the Summit X460 switches running?

Ldp is multicast based. Not sure if extremes support tldp. ?

Andreas,

The LDP hello packets are indeed transmitted via multicast to all routers (224.0.0.2) but the session is established via unicast.

LDP is supported on select platforms, with the Summit X460 being one of them. We can see in the configuration provided in the body of the post that LDP is enabled.

Well then you need multicast routing on the routers between the ldp nodes ?

Are you saying there's no MPLS on the routers in-between your routers?

Correct.

So you're sending an MPLS frame to non-MPLS capable routers? How do you plan to setup an MPLS LSP? Am I missing something here?
Grosjean, Stephane wrote:

The end points will be MPLS routes but the in between routes will not. It was my understanding that the in between router would pass the MPLS traffic. If you read below you will see the LDP peers are operational. But vpls l2vpn shows in a signeling state and does not coma active. Thanks for any HELP!

Sorry for not following closely this thread (vacations...). The Targeted LDP adjacency can come Up across an IP backbone, no problem, but the transport is impossible without MPLS LSP in the backbone. I'm afraid you're trying to do something not possible.

Hi Matt,

The LSR ID of the MPLS routers should be a routed loopback address(/32 and loopback enabled). In your case, the LSR ID should be of the VLAN which is lpbk since it has a /32 address.

Following are the changes that is required.

Switch #1 name ldc-xm0-nsw012

#
# Module mpls configuration.
#
configure mpls add vlan "lpbk"
enable mpls vlan "lpbk"
enable mpls ldp vlan "lpbk"
configure mpls add vlan "snj_si0-bkd022"
enable mpls vlan "snj_si0-bkd022"
enable mpls ldp vlan "snj_si0-bkd022"
configure mpls lsr-id 192.168.0.1
enable mpls protocol ldp
enable mpls
create l2vpn vpls ldc-snj-vpn fec-id-type pseudo-wire 25
configure l2vpn vpls ldc-snj-vpn add service vlan ent_sp0-int001
configure l2vpn vpls ldc-snj-vpn add peer 192.168.0.2 core full-mesh

Switch #2 name snj-xm0-nsw010
You will need to change the lpbk VLAN address to a different IP say 192.168.0.2.

#
configure mpls add vlan "lpbk"
enable mpls vlan "lpbk"
enable mpls ldp vlan "lpbk"
configure mpls add vlan "snj_si0-bkd022"
enable mpls vlan "snj_si0-bkd022"
enable mpls ldp vlan "snj_si0-bkd022"
configure mpls lsr-id 192.168.0.2
enable mpls protocol ldp
enable mpls
create l2vpn vpls ldc-snj-vpn fec-id-type pseudo-wire 25
configure l2vpn vpls ldc-snj-vpn add service vlan ent_sp0-int001
configure l2vpn vpls ldc-snj-vpn add peer 192.168.0.1 core full-mesh

Please make this change and let us know if it helps!
Thanks Prashanth. I found two issues with my config. I did not have routing between the loopback and a vlan tag was incorrect. I've made the change you recommend and fix the routing issue and vlan tag, I did use diffrent IP for the loppback to better fit into our network.

I do see the end points operational.

Hi Matt,

Good to know that some misconfigs have been sorted out.
If the MPLS peers are operational, there should be a transport LSP for the peer automatically in the VPLS instance. Try re-configuring the L2VPN and check if it helps!

Also, please refer the article below for a sample VPLS configuration.

How to configure VPLS session in Extreme Switches using LDP

Hope this helps!
Hi Prashanth, thank you again... I've stripped the configuration out of MPLS & LDP & OSPF and started over again and used you doc "How to configure VPLS session in Extreme Switches using LDP". I've triple checked the confing and I'll still getting to the same point "Signaling (No transport LSP)".

Hi Matt,

The configuration part looks fine to me for both the peers. Looking at the iproute output, I get an impression that there are other routers in the path. Can you confirm that? Are these devices running MPLS too? We may not have the proper LSPs for every next-hop. may be that is why, the signaling is not active.

#oa 172.31.30.0/24 172.31.22.251 12 UG-D---um--f- snj_si0-bkd022 0d:3h:22m:13s
#oa 172.31.55.0/24 172.31.22.251 12 UG-D---um--f- snj_si0-bkd022 0d:3h:22m:13s

if these are third party devices, is it possible to configure the MPLS on these devices and check if that helps!

Hi Prashanth, see my reply in the string below... thanks again for your help.
Hi Prashanth, yes there is routers in between there are X450a with only Advanced Edge licening so I can't enable MPLS. I would think that the X450a would pass the MPLS traffic? Is there something that would stop them from doing so?

Thanks again, Matt

Prashanth, I wonted to add that was checking the advertising of each of the routers. I'm seeing a diffrence on the two routes.

snj-xm0-nsw010.8 # sh mpls ldp label advertised

Advertised Destination Label Peer NHop
Label Mapping Flags Label Type NextHop Name
-------------------------------------------------------------------------------
0x00434 192.168.122.1/32 -LE -- vlan lpbk --

(M) Multiple Next Hops

ldc-xm0-nsw012.9 # sh mpls ldp label advertised

Advertised Destination Label Peer NHop
Label Mapping Flags Label Type NextHop Name
-------------------------------------------------------------------------------
0x00434 192.168.122.1/32 2LE -- VPLS -- vpls-ldc-bkd55

Is this some ting to look into?

Thanks Matt

Hmm not a MPLS expert but when we need to pass MPLS framing at layer 2 across a non-mpls switch then we build a vman and enable jumbo frames on the per layer 2 switches to tunnel the mpls traffic through. On the 450's there are some restrictions if you want to pass standard tagged vlans and vmans on common trunk ports. Not sure if this will help or confuse

Thanks, one limitation is that I can not enable jumbo packets the the wan link does not support jumbo packets.
