I have a 2620 with a FastEthernet attached to Cat5K on port 2/12.
Speed and duplex have been forced to 100/Full on both sides. There is an
ISL trunk between them.
I have two sub-interfaces on the 2620 FA0/0.100 and FA0/0.300 for VLANs
100 & 300 respectively. I created a bridge group on the 2620 and setup
IRB with a BVI interface. The IP addresses are 172.16.135.14/28 on the
BVI and for the 5K it is 172.16.135.2/28 in vlan 100. My switch can't
ping the 2620 and the 2620 can't ping the switch. When I debug ip packet
on the 2620 I get a encapsulation failed from the BVI interface. I was
under the impression the BVI would be able to ping the switch.
I have two other routers attached one on VLAN 100 and the other on VLAN
300 but both on the 172.16.135.0/28 network. They can ping each other
and the switch. I know the bridging is working I just don't fully
understand why the BVI interface itself can't ping anything on the same
network.
