cisco as bridge


What is required to setup transparent bridge on two eth ifaces ? I tried the following:

bridge irb ! interface Ethernet0 no ip address no ip proxy-arp bridge-group 1 ! interface FastEthernet0 no ip address no ip proxy-arp bridge-group 1 !

but it was not working. Additionally, where should I assign IP to get access to it from both sides (for telnet)?

best regards Jarek

In such case cisco screams about overlapping. Do you thing it is meaningless ???

Do not use IRB

no bridge irb

bridge 1 protocol ieee

interface Ethernet0 bridge-group 1

interface FastEthernet0 bridge-group 1

You don't need to use IRB if all you need is transparent bridging. However, if you need to also telnet the bridge itself using telnet from the bridged ethernet segments then you will need to use IRB.

You need to add the following to your config to get this working

bridge 1 protocol ieee bridge 1 route ip ! interface BVI 1 ip address

And then:

interface BVI 1 description bridge virtual interface ip address x.x.x.x m.m.m.m

To assign an IP address to a virtual address assigend to bridge-group 1
