[f-nsp] Cannot ping VRRP IP when backup active

[Tamas Csillag]

As I know, VRRP does not support icmp echo replies on the virtual IP. 
The owner replies because it has a physical interface with the same IP, 
however if a backup becomes active, it'll only have the virtual IP, so 
it won't answer.
One of the things Brocade always announces about it's VRRP-E is that it 
always replies to ping.
Most vendors provide a config statement to enable pinging the virtual 
IP, but that's not strictly following the RFC.

The master has my .1 address, and all works fine,  If I shutdown the VE interface on the master for testing, in a few seconds routing resumes on the VE interface of my backup router.  However, I never can ping the same .1 address while the backup router is active.  Re-enable the master VE interface and I can ping .1 again, and of course the hosts are still happy.
