I've been working with a client trying to get this working. We tried 12.2(31)SB6, 12.4(15)T1 IP Services and 12.4(15)T1 Advanced IP Services.
It works fine for Ethernet to Ethernet, or Ethernet to VLAN, but it doesn't work for VLAN to VLAN either on the same interface or on different interfaces. We've tried this on both a Cat5505 as well as a Cat294XL thinking that maybe there would be some issues with one platform or the other.
Here's an example:
! VXR (12.4(15)T1 Adv. IP Services)
!
interface GigabitEthernet0/1
no ip address
duplex full
speed 100
media-type rj45
no negotiation auto
!
interface GigabitEthernet0/1.202
encapsulation dot1Q 202
!
interface GigabitEthernet0/1.203
encapsulation dot1Q 203
!
connect test GigabitEthernet0/1.202 GigabitEthernet0/1.203
! Cat 5505
!
set vlan 202 9/1
set vlan 203 9/2
set port name 9/1 PC1
set port name 9/2 PC2
set port name 9/3 VXR-G0/1TRUNK
clear trunk 9/3 1-201,204-999
set trunk 9/3 on dot1q 202-203,1000-1005
!
We seem to be able to sequeeze a few packets through every once in awhile - like 1 or 2 every 20 or 30 packets:
64 bytes from 192.168.1.1: icmp_seq=10 ttl=64 time=0.604 ms
64 bytes from 192.168.1.1: icmp_seq=18 ttl=64 time=0.638 ms
64 bytes from 192.168.1.1: icmp_seq=40 ttl=64 time=0.621 ms
64 bytes from 192.168.1.1: icmp_seq=48 ttl=64 time=0.608 ms
64 bytes from 192.168.1.1: icmp_seq=70 ttl=64 time=0.605 ms
64 bytes from 192.168.1.1: icmp_seq=78 ttl=64 time=0.630 ms
As you can see from the below show interface, the interface is receiving lots more packets than it's sending:

Does L2VPN Local Switching VLAN to VLAN not work on VXRs or something?
This link seems to indicate that E-E VLAN is supported in 12.4(11)T.
