Hi folx,

a hardware address of 00:00:5e:00:01:55 is "translated" into:

Ethernet II, Src: IETF-VRRP-virtual-router-VRID_55
                       ^^   ^^^^^^^^^^^^^^ ^^
That's 3 times "Virtual Router"!

from: http://www.faqs.org/rfcs/rfc3768.html :


7.3.  Virtual Router MAC Address

   The virtual router MAC address associated with a virtual router is an
   IEEE 802 MAC Address in the following format:

      00-00-5E-00-01-{VRID} (in hex in internet standard bit-order)

   The first three octets are derived from the IANA's OUI.  The next two
   octets (00-01) indicate the address block assigned to the VRRP
   protocol.  {VRID} is the VRRP Virtual Router Identifier.  This
   mapping provides for up to 255 VRRP routers on a network.


So the complete 00-00-5E-00-01 is assigned to VRRP and 
there's no other VRRP in wireshark-1.2.9/manuf .

Therefore it should be save to shorten the description into 
VRRP_VRID or even only VRID .
