Hi everyone. I'm doing some preliminary testing in our lab in order to deploy EoMPLS on our ethernet network but I've run into a little bit of a snag and was wondering if anyone could clarify something for me.
The setup I have is 3550---7603-SUP32---7204VXR---3550 I have VLAN 800 setup to cross from one 3550 to the other. The relevant portions of the config are as follows: 7603: interface GigabitEthernet2/2 description to 3550 switchport switchport trunk encapsulation dot1q switchport trunk allowed vlan 800 switchport mode trunk no ip address load-interval 30 ! interface Vlan800 xconnect 10.0.1.4 800 encapsulation mpls ! interface GigabitEthernet1/1 description 7603 to 7204 switchport switchport trunk encapsulation dot1q switchport trunk allowed vlan 220 switchport mode trunk no ip address load-interval 30 ! interface Vlan220 ip address 10.0.0.18 255.255.255.252 load-interval 30 tag-switching mtu 1520 tag-switching ip ! 7204VXR: interface FastEthernet1/0.220 encapsulation dot1Q 220 ip address 10.0.0.17 255.255.255.252 ip ospf cost 40 tag-switching mtu 1520 tag-switching ip ! interface FastEthernet3/0.800 encapsulation dot1Q 800 xconnect 10.0.1.1 800 encapsulation mpls ! Now when I do a "show mpls l2 vc" I can see the circuit up from the 7204 side but down from the 7603 side. I think I have everything setup properly but can't figure out why it wouldn't work. If I change things around a bit and reconfigure the 7603 to use sub-interfaces with dot1q instead of vlan interfaces like this: interface GigabitEthernet2/2.800 encapsulation dot1Q 800 xconnect 10.0.1.4 800 encapsulation mpls ! The circuit is up from both ends and pings from/to each 3550 are successful: frort01-lab#sh mpls l2 vc Local intf Local circuit Dest address VC ID Status ------------- -------------------- --------------- ---------- ---------- Gi2/2.800 Eth VLAN 800 10.0.1.4 800 UP 7603-lab# Is this the only way to get EoMPLS to work between these two devices? I'm sure I've seen the xconnect command used on VLAN interfaces before and it has worked fine. Any thoughts or comments would be greatly appreaciated. Thanks.
