[j-nsp] VRRP max group limit?

[Gary Tate]

 From what I can remember from the RFC there are only groups 0-255 
allowed per broadcast domain - they may have updated that since I last 
read it.

group-number—VRRP group identifier. If you enable MAC source address 
filtering on the interface, as described in Configure MAC Address 
Filtering, you must include the virtual MAC address in the list of 
source MAC addresses that you specify in the source-address-filter 
statement. MAC addresses ranging from 00:00:5e:00:01:00 through 
00:00:5e:00:01:ff are reserved for VRRP, as defined in RFC 2338. The 
VRRP group number must be the decimal equivalent of the last hexadecimal 
byte of the virtual MAC address.
Range: 0 through 255

Its tied to the VRID and the MAC address so I dont think it will be changing
