[c-nsp] Cisco 1841 simple bridging

[Pablo Almido]

Hi folks, I am trying configure simple bridging in a router 1841, because I
need that it works in mode bridge, I will put I firewall beetween this
router and ISP router, and I want to use QoS features of cisco router 1841,
it is possible configure in router cisco1841, how I can reach it?

Router ISP ---------      Router 1841  (bridge) ------------  Firewall

I have execute the following commands, but I get a error.

router(config)#bridge 1 protocol ieee
router(config)#bridge irb
router(config)#int fa0/0/0
router(config-if)#bridge-group 1
FastEthernet0/0/0 does not support bridging
router(config-if)#exit


thanks in advance.
