Yes, it is a VRRP address.  The RFC for VRRP (at 
http://www.faqs.org/rfcs/rfc2338.html ) says:

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.


This is a VRRP MAC address.  Whether it's a Nokia or other VRRP-speaker 
we don't know.
