Loopback Interface

Under what circumstances loopback interface will be of no importance even if configured properly?

Re: Loopback Interface

Loopbacks are only important if they are used.

If the loopback is not in the routing table of other routers or otherwise unreachable, it is unimportant.

Loopbacks are more important if there are redundant paths.

Loopbacks are used extencively for OSPF, Vioce, DLSW and BGP.
