What is VRRP
● Virtual Router Redundancy Protocol
● Provides for automatic assignment of available Internet Protocol (IP) routers
to participating hosts
● Increases the availability and reliability of routing paths via automatic default
gateway selections on an IP subnetwork
● Consist of master and slave node
● Provides information on the state of a router, not the prefixes
● Available on single subnet with direct connection between nodes
● Support IPv4 and IPv6
● Described in IETF RFC 5798

VRRP topology
9
● Master router is forwarding
traffic
● There is an additional virtual IP
on master
● The virtual IP is acting as
gateway
● Virtual IP should use /32
● When master fail, slave will
become Master router
● Virtual IP will move to master
router

● VRRP on public interface will waste IP
addresses :-(
● Usually is applied on LAN side
