INTER-AS-VPLS

belalcciejo · ‎06-04-2012

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

Hello,

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

hi Friend,

could you possible to send me one completely configuration file ? many thanks!
