bridging interfaces

[lavanya_cisco]

hello

I have a 2600/3600 router with 2 LAN interfaces. my customer told, we can bridge these 2 interfaces and logically make it as 1 interface on layer 3.. can this be done ? any configs ? how else can bridging be useful on routers ?

thanks a lot. the webpage really helped.. just to make myself clear, in example 1 and 2, the PCs and servers will be on the same LAN, right ? i mean on the same IP subnet ?? is this the case even for bridging over WAN ?? will both the LAN on either side of the wan be on the same IP subnet ?
