WHAT IS THE FUNCTION OF L2 ROUTER IN IS-IS NETWORK
Posted on 2004-09-02
According to my understanding
In IS-IS L1 ROUTER EXHANGE ROUTES WITH L1 ROUTERS
L1 routers talk to L1-L2 routers to get out of their own area
If this this correct, then what is the function of L2 router, also what do L1 routers talk about to L1 routers in the same area and what is the need there for them to talk ?
