VRRP and VRRP for IPv6 Overview

For Ethernet, Fast Ethernet, Tri-Rate Ethernet copper, Gigabit Ethernet, 10-Gigabit Ethernet, and Ethernet logical interfaces, you can configure the Virtual Router Redundancy Protocol (VRRP) and VRRP for IPv6. VRRP and VRRP for IPv6 allow hosts on a LAN to make use of redundant routing platforms on that LAN without requiring more than the static configuration of a single default route on the hosts. The VRRP routing platforms share the IP address corresponding to the default route configured on the hosts. At any time, one of the VRRP routing platforms is the master (active) and the others are backups. If the master fails, one of the backup routers becomes the new master router, thus always providing a virtual default routing platform and allowing traffic on the LAN to be routed without relying on a single routing platform.

VRRP is defined in RFC 3768, Virtual Router Redundancy Protocol.

For VRRP and VRRP for IPv6 overview information, configuration guidelines, and statement summaries, see the JUNOS High Availability Configuration Guide.
