Hi, Would anybody have any comments on doing port-mode EoMPLS xconnects on port-channels on Sup720 running SXI?
We're contemplating delivering EoMPLS PtP this way. In or "normal" setup we connect a "switchport trunk" from the downlink device to a port-mode EoMPLS-port, plain and simple. My guess is that there's nothing wrong with doing this via port-channels instead. It seems to work, and the documentation hints at it being supported[1] but is it a bad idea for some reason? Example configuration from the "normal" setup: ! *** CE device *** interface GigabitEthernet0/24 description Uplink to PE1 Gi1/1 switchport trunk encapsulation dot1q switchport mode trunk switchport nonegotiate ! ! *** PE device *** interface GigabitEthernet1/1 description Downlink to CE1 Gi0/24 mtu 9216 no ip address udld port disable xconnect 192.0.2.10 1234 encapsulation mpls ! We would like to do something like this: ! *** CE device *** interface GigabitEthernet0/23 description Uplink to PE1 Gi1/1 switchport trunk encapsulation dot1q switchport mode trunk switchport nonegotiate channel-group 1 mode on ! interface GigabitEthernet0/24 description Uplink to PE1 Gi1/2 switchport trunk encapsulation dot1q switchport mode trunk switchport nonegotiate channel-group 1 mode on ! interface Port-channel1 description Uplink to PE1 Po1 switchport trunk encapsulation dot1q switchport mode trunk switchport nonegotiate ! ! *** PE device *** interface GigabitEthernet1/1 description Downlink to CE1 Gi0/23 no ip address channel-group 1 mode on ! interface GigabitEthernet1/2 description Downlink to CE1 Gi0/24 no ip address channel-group 1 mode on ! interface Port-channel1 description Downlink to CE1 Po1 no ip address xconnect 192.0.2.10 1234 encapsulation mpls ! This is without relevant MTU adjustments and so on. Just the EoMPLS configuration.
