It seems I can't get an EoMPLS link between two devices to work...It looks like I'm seeing all the mac-addresses on one side, but not the other. Very odd. In any case, I was wondering if anyone could verify my configuration.
Router A (6524) - Seeing all MACs
interface vlan 111
xconnect 10.1.1.111 111 encapsulation mpls
mtu 1534
RouterA#show mpls l2transport binding 38
Destination Address: 10.1.1.111, VC ID: 111
Local Label: 71
Cbit: 1, VC Type: Eth VLAN, GroupID: 0
MTU: 1534, Interface Desc: ABC
VCCV Capabilities: Type 2
Remote Label: 167
Cbit: 1, VC Type: Eth VLAN, GroupID: 0
MTU: 1534, Interface Desc: ABC
VCCV Capabilities: Type 1, Type 2
Router B (7304) - Seeing only local MACs
interface Gigabit0/1.111
encapsulation dot1q 111
xconnect 10.1.1.222 111 encapsulation mpls
RouterA#show mpls l2transport binding 38
Destination Address: 10.1.1.222, VC ID: 111
Local Label: 167
Cbit: 1, VC Type: Eth VLAN, GroupID: 0
MTU: 1534, Interface Desc: ABC - EoMPLS
VCCV: CC Type: CW [1], RA [2]
CV Type: LSPV [2]
Remote Label: 71
Cbit: 1, VC Type: Eth VLAN, GroupID: 0
MTU: 1534, Interface Desc: ABC
VCCV: CC Type: RA [2]
CV Type: LSPV [2]
I'm thinking this could be a code level issue...

Hello Jeff,
but user traffic flows in both directions, only in one direction or in none direction over the EoMPLS link?
Hope to help

Traffic should be flowing in both directions. It appears that traffic is flowing correctly one-way. I'm assuming this based on the ability to see mac-addresses on one-side, but not the other.

Hello Jeff,
the sense of my question was exactly to understand if this had impact on service or not.
When I tested EoMPLS on GSR routers with 3GE engine 2 linecards we noticed that MAC learning was disabled :
even sending frames with dest MAC = GE port MAC the frames were transported over the tunnel to the remote side.
So it is possible that you don't see any MAC learning on the c7301 but the service is working fine.
c6524 implementation can be different and allows you to see the "learned" MAC addresses on the EoMPLS access link.
Hope to help

I understand.
Sadly, the service is still not functioning correctly.

Hello Jeff,
could L2TPv3 be used instead ? It supports also 802.1Q Vlans
Hope to help
