VRRP - IP Protocol

This page provides IP protocol information on the Virtual Router Redundancy Protocol (VRRP) detected by the Netify DPI engine. Please see the IP protocol catalog for information on other IP protocols.

VRRP is the Virtual Router Redundancy Protocol, letting a group of routers share a virtual IP address so a backup router can transparently take over on failure. Linux has a native handler for this IP protocol.

VRRP is used by redundant router pairs to share a virtual gateway IP for failover; allow only on internal network segments running VRRP between designated routers.
