[c-nsp] Prevent "IP Spoofing" from inside of the network

[ricardo.jantarada at bnpparibas.com]

Hi,

A few days ago, someone accidentally took the HSRP IP Address of the
network.
We usualy use DHCP protocol, for clients, to protect the network for this
kind of problems, but sometimes we have to use Hard IP addresses for other
diveses.
I would like to protect this HSRP IP address to be use by someone else than
my routers.

PS: sorry for my english ;)

Ricardo
