How to recognise a Virtual Router ID by MAC address?
Virtual Router redundancy protocol is a standard protocol which helps group a number of routers into one virtual router in order to increase availability and reliability of routing paths
Summary
Range or Prefix
Application
00:00:5E:00:01:00 - 00:00:5E:00:01:FF
IPv4 Virtual Router Redundancy Protocol
00:00:5E:00:02:00 - 00:00:5E:00:02:FF
IPv6 Virtual Router Redundancy Protocol
Detection Rule
If the MAC address looks like 00-00-5E-XX-XX-YY, where XX is 00-01 (for IPv4 frames) or 00-02 (for IPv6 frames), YY will be Virtual Router Identifier.
This mapping provides for up to 255 IPv4/IPv6 VRRP routers on a network.
