Hi,
I am trying to bridge two VLANs (vlan 20 and vlan 30) using 3550 as a layer
two switch. Router1 is on VLAN 20 and VLAN 30 is an internal VLAN in 3550
(similar to Sc0). Router12 is doing IRB/trunking. From R12 (BVI) I can ping
VLAN30 interface (in the switch) and R1 (bothways) fine. But I can not make
VLAN30 interface (in switch) to ping R1. Is this be possible? If yes, am I
missing anything?
R1---VLAN20---3550---Trunk---R12
Here are the relevant portion of the configs:
