Tim, you have 2 vlan's (16 and 36) in the same bridge domain so not sure if
bridging IP between both interfaces will work.
Also, how are R1 and R3 physically connected ? Into the same switch as R6 ?
One on VLAN 16 and the other on VLAN 36 ?

Hi guys,

Here's the scenario.

R1 <--> R6 <-->R3

R6 has a BVI 1 configured and R6's fa1/0/0 is trunking. Here's the config:

bridge irb

interface FastEthernet1/0/0
 no ip address
 half-duplex
!
interface FastEthernet1/0/0.16
 encapsulation dot1Q 16
 bridge-group 1
!
interface FastEthernet1/0/0.36
 encapsulation dot1Q 36
 bridge-group 1

interface BVI1
 ip address 136.7.136.6 255.255.255.0

bridge 1 protocol ieee
bridge 1 route ip

R6 can ping both R1 and R3, but R1 can't ping R3. There are no acl's or any
other obvious (at least to me) reasons for this. I assume R1 should be able
to ping R3. Can someone help me out?

Thanks in advanced, Tim
