Hi All,
On 7606 with RSP720, I've configured bunch of eompls circuits. This is a multivendor equipment lab but There is also one circuit towards another 7600 box.
7601 and 7602 is directly connected. 7601 ( Lo 2.2.2.2) . 7602 (Lo:17.17.17.2) Both are running 12.2(33)SRD6
At 7601 "show mpls l2transport vc" command does not list the xconnects.
7601:
7601# show mpls l2transport vc
Local intf Local circuit Dest address VC ID Status
------------- -------------------------- --------------- ---------- ----------
7601#
I can see the xconnects via:
7601#show xconnect all
Legend: XC ST=Xconnect State S1=Segment1 State S2=Segment2 State
UP=Up DN=Down AD=Admin Down IA=Inactive
SB=Standby RV=Recovering NH=No Hardware
XC ST Segment 1 S1 Segment 2 S2

At 7602, I can see that there is no remote binding with 7601:

It's weird not to see any output at "show mpls l2transport vc" command at 7601. Does anyone have any idea?

Did you ever get this issue resolved? I too am having the same issue on a 7604 running 12.2(33)SRE5. It was working fine yesterday and this morning none of my xconnects will bind.

Nope, I think I'll have to open a TAC case for this.

Hi,
I upgraded my router for another purpose and it is resolved. It definitely looks like a bug.
