Hello!
I have some problem with xconnect in the follow scheme:
Cisco 6524:
interface Port-channel115.179
encapsulation dot1Q 179
xconnect 10.240.0.2 20179 pw-class PW_MPLS
end
Cisco 7606:
interface GigabitEthernet3/0/2.179
encapsulation dot1Q 179
xconnect 10.240.0.4 20179 pw-class PW_MPLS
end
My problem:
When I try to ping host-2 from host-1 I get ping request timed out. I this case I can see send packets to xconnect on Cisco 6524 and receive packets on the Cisco 7606. And I have arp-entry for host 192.168.255.15 in the arp-table on host-2.
When I try to ping host-1 from host-2 I get ping request timed out too. But I haven’t send packets to xconnect on Cisco 7606 and receive packets on Cisco 6524.
How I can understand - it’s well traffic forwarding from host-1 to host-2, but nothing from host-2 to host-1.
If I did “ping mpls pseudowire 10.240.0.4 20179“ from Cisco 7606 - all ok (I can see send packets on Cisco7606).

In what could be the problem?
P.S. And sorry my poor English...
