I have Cat3850 will connected to other switch with PortChanel1(trunk all) and PortChanel2(trunk all) to another switch.
From po1 i got 2 vlans 10,20 and from po2 got vlan 30
Config of vlan intf:
int vlan 10
ip addr 10.10.10.1 255.255.255.252
int vlan 20
no ip address
xconnect vfi 20
int vlan 30
ip address 10.30.30.1 255.255.255.252
When mpls traffic goes from vlan 30(po2), thats work perfectly, xconnect work, when mpls traffic goes from vlan 10 on po1 and then they must be return to po1 in 20 vlan, it not work, xconnect status UP, i see remote mac on 3850 in sh mac add vlan 20, but they dont send it through po1. Maybe i'm dont known something?
