Dear ,

I’m trying to configure INTER-AS VPLS as the attached topology the ASBR1:Cisco IOS , PE1:ASR9K and ASBR2:Juniper MX

The L2vpn BGP Multi-hope BGP is up and I can see the label swapping form the both end but the VC is down

Hi ,

I will share my experience in this

Due to my requirements to have Mnulti-hope L2 vpn signaling between ASBR2 and PE1 I used this RFC option C   http://tools.ietf.org/html/rfc4761#section-3.4

ASBR1: Junos MX

ASBR2:Cisco 7600( you can’t run VPLS BGP signaling on this router you need extra card ES+ because of this I used method C )

PE1:ASR9K

The configuration as below

  • •1-      As100 running LDP and AS200 running RSVP
  • •2-      Send the label unicast using BGP between ASBR1&ASBR2 and advertise the Loopback ip addresses of PE1,ASBR1 & ASBR2 between each other using BGP

From cisco : neighbor ASBR2 address send-label

From Juniper side :

type external;

family inet {

   labeled-unicast {

       resolve-vpn;  // you need to insert this command to make the LSP up inside inet.3 table

   }

}

neighbor ASBR1 address

  • •3-      Inside ASBR1 you need to redistribute the ASBR2 inside the IGP

  • •4-      Multi-hope L2vpn signaling between the PE1 & ASBR2

type external;

multihop;

local-address 192.168.255.3;

family l2vpn {

   signaling;

}

neighbor  PE1 loopback Ip

form ASR:

!

af-group L2VPN address-family l2vpn vpls-vpws

route-policy pass-all in

route-policy pass-all out

session-group L2VPN

remote-as 65500

ebgp-multihop 255

update-source Loopback200

neighbor-group L2VPN

use session-group L2VPN

address-family l2vpn vpls-vpws

   use af-group L2VPN

neighbor ASBR2 loopback IP

use neighbor-group L2VPN

  • •5-      VPLS configuration :

Form Juniper:

show routing-instances MPLSL2VPN-INTER-AS

instance-type vpls;

interface ge-11/0/1.70;

route-distinguisher 200:800;

vrf-target target:200:800;

protocols {

   vpls {

       traceoptions {

           file MPLSL2.log;

           flag all;

       }

       site-range 10;

       mac-table-size {

           16;

       }

       interface-mac-limit {

           8;

       }

       no-tunnel-services;

       site 1 {

           site-identifier 1;

           interface ge-11/0/1.70;

       }

   }

}

Form ASR side :

l2vpn

autodiscovery bgp

signaling-protocol bgp

   mtu mismatch ignore //// you need this command very very necessary as without this the PW will not become UP

!

bridge group MPLSL2VPN-INTER-AS

bridge-domain MPLSL2VPN-INTER-AS

   interface GigabitEthernet0/0/0/0

   !

   vfi L2VPN

   vpn-id 2

   autodiscovery bgp

     rd 200:800

     route-target 200:800

     signaling-protocol bgp

     ve-id 2

     !

   !

   !

Hello,

Thx a lot for this output. I fixed my VPLS between NCS540 and Juniper using "mtu mismatch ignore".
