Does the MTU match on both ends please?
You can see the MTU on both ends in the output of the cmd “sh mpls l2 vc det”

I've found another thread where you were talking about router pw on an ASR1k.

He is the config i've done so far :

ASR 1001X :

l2 vfi TEST2 manual
 vpn id 258
 bridge-domain 4093
 neighbor 2.2.2.2 11 encapsulation mpls

interface BDI4093
 mtu 1530
 ip vrf forwarding TEST2
 ip address 172.31.0.253 255.255.255.0
 standby 1 ip 172.31.0.254
 standby 1 priority 110
 standby 1 preempt delay minimum 60
end

interface GigabitEthernet0/0/4
 no ip address
 load-interval 30
 negotiation auto
 service instance 4093 ethernet
  encapsulation dot1q 4093 exact
  rewrite ingress tag pop 1 symmetric
  bridge-domain 4093
 !


ISR 2801 :

interface FastEthernet0/1.4093
 encapsulation dot1Q 4093
 no cdp enable
 xconnect 1.1.1.1 11 encapsulation mpls


//

For some reason the xconnect is not coming up...


RTI-MPLS-SAB-01#sh xconnect all
DN pri  vfi OCTEY                        UP mpls 2.2.2.2:11<http://2.2.2.2:11>               DN
UP pri   bd 4093                         UP  vfi TEST2                        UP


Thanks for your help.

Hi Adam,

I don't have the xconnect command under the bdi interface :

RTI-MPLS-SAB-01(config)#interface BDI4093
RTI-MPLS-SAB-01(config-if)#xconnect ?
% Unrecognized command

I'm using ASR1001X , ves 03.13.01.S


Any thought ?

Hi Nicolas,

This is the config for mixing EFPs and PWs in a common BD + IP interface for the BD.
Manual hub and spoke type of configuration with IP address + VFR at the hub location.

interface TenGigabitEthernet0/3
 mtu 9000
 service instance 8000 ethernet
  description CUSTOMER-B
  encapsulation dot1q 20,30,40
  rewrite ingress tag pop 1 symmetric
  bridge-domain 8000

interface BDI8000
 mtu 9000
 vrf CUST-B
 ip add 192.0.2.1 255.255.255.0
 xconnect vfi CUST-B-BD

l2 vfi CUST-B-BD manual
 vpn id 1
 neighbor 10.0.1.3 100 encapsulation mpls
 neighbor 10.0.1.4 200 encapsulation mpls
 neighbor 10.0.1.5 300 encapsulation mpls

Spokes would have just EFPs with xconnect.
