Hi Senthil,


Bridge groups provide a method to group two or more ports into a single broadcast domain, where as VLAN's provide a method to group many ports into a single broadcast domain or establish a number of broadcast domains (or secure groups) on a single switch.


Bridge groups operate at layer 2. So they are not very effective at connecting layer 3 switches and routers.If you want to connect 2 ports of a layer 2 switch with 2 Ethernet interfaces of a router you can do that but the Ethernet interfaces on the router no longer operate as routed interfaces.
