NetBios Name-Caching is an older feature which was used in conjunction with RSRB
and Local Acknowledgement. The cache that DLSw+ keeps for NetBios names is a
completely different cache, optimized for DLSw+ operation. By configuring 'dlsw
icanreach netbios-name ...' on a router, it advertises to its peers via capabilities exchange
that it has a route to the NetBios station in question, thereby creating static remote entries
in each of its remote-peers. This is the configuration you will most likely want to use.
