[c-nsp] Finding the root bridge

[Victor Sudakov]

A convenient way to identify the root bridge without logging in to a lot
of switches to figure out their addresses. Works only if you have
VTPv3 enabled.

sw-bptoik#sh spanning-tree vlan 22 | i Address
             Address     4403.a7c9.a780

[dd]

sw-bptoik#sh vtp devices | i 4403.a7c9.a780
VLAN         No   35       e4d3.f1cc.f280 4403.a7c9.a780 sw-sem
sw-bptoik#

So "sw-sem" is the root brigde.
