bridge-group <id> on interface vlan

Level 1

Hi all,

i configured a bridge-group "29" between interface vlan 1 and the dlsw peer of a cisco 1801 router.

When i put the command on "interface vlan 1", the ip interface vlan don't replay to icmp echo request message; i try to ping the real ip (no standby ip):

________

interface Vlan1

ip address 172.20.10.2 255.255.255.0

standby 1 ip 172.20.10.1

standby 1 priority 255

standby 1 preempt

standby 1 track FastEthernet0 40

bridge-group 29

________

Something know if is this a bug or is a normal situation?

Thank you

Diego

Just curious, were you able to ping the 172.20.10.1 IP?

I believe you wont be able to route and bridge on the same interface. (unless IRB is configured)

Could you give us the other part of your configuration?

Cant you use a BVI instead?

I can ping the virtual ip address and the device routes and bridge on the same interface. Only icmp echo reply on real ip address doesn't work.

I tried with a debug ip packet detail, and i don't see nothing when ping the real ip.

Only if i ping the virtual ip i see the icmp echo request and reply.

I think that is not a configuration problem. Maybe need to add a command on the vlan interface configuration.

however, this is the config:

service timestamps debug datetime msec localtime

service timestamps log datetime msec localtime

service password-encryption

no service password-recovery

end

Thanks

for this to work there are three things need to be enabled

1.bridge irb

2.bridge protocol ieee

3.bridge route ip

hope this might help

These don't resolve my issue.
