I am using an external router R1 with 3550 emi version,
R1 has a trunk port to 3550 with VLAN 20 (E1.1) and VLAN 40 (E1.2)
R2 on VLAN 20.
R3 on VLAN 40.
I enabled bridging on R1's subinterface Eth 1.1 and Eth 1.2, now R2 and R3 can
ping each other, so the bridge does work fine.
Then I created an interface vlan 40 on 3550, from 3550 I can ping R3 and R1's
BVI interface; however, I can't ping R2 which is on VLAN 20.
I guess it's a MAC issue. Does anyone know what's the problem?
Thanks
