Describes how to implement the Virtual Router Redundancy Protocol (VRRP) to enable transparent failover at the first-hop IP router by allowing a group of routers to act as a single virtual router.
VRRP
This topic describes the Virtual Router Redundancy Protocol (VRRP), which allows a group of routers to form a single virtual router and provides transparent failover at the first-hop IP router.
VRRP over physical and bundle interfaces
This topic describes VRRP support for IPv4 and IPv6 networks on physical interfaces, physical sub-interfaces, bundle interfaces, and bundle sub-interfaces, including supported scale and topology.
Unicast VRRP
This topic describes how VRRP supports Layer 3 unicast transport mode to enable high availability in cloud network scenarios where Layer 2 multicast or broadcast transports are not supported.
VRRP over BVI
This topic describes how VRRP runs over Bridge-Group Virtual Interfaces (BVIs) to provide default gateway redundancy for a LAN, including supported scale and topology.
VRRP statistics
This topic describes the VRRP statistics that you can view or clear for one or all VRRP groups or Virtual Router IDs (VRIDs) to monitor VRRP health and debug VRRP issues.
