From the VRRP RFC: 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. Since IANA comes from DARPA, it's not particularly surprising that the manufacturer would be listed as the U.S. Department of Defense. However, the relationship between DARPA and IANA is less direct now and the influence of large corporations is increasing - it's probably more technically accurate to list "The Military-Industrial Complex" as the manufacturer.
