Overview of VRRP Support in NSM

236
The VRRP feature allows you to use redundant routers on a LAN by configuring a single
default route on the host. All VRRP routers share the IP address corresponding to the
configured default route. One of the VRRP routers acts as the master and the others are
backups. If the master fails, one of the backup routers becomes the new master, providing
a virtual default router, and ensuring that traffic on the LAN is continuously routed.
The NSM implementation of VRRP has the following limitations:
WAN and serial interfaces cannot support VRRP. VRRP requires Ethernet or gigabit
interfaces.
A single interface can support only two VRRP groups.
You can enable a VRRP group only on a single interface.
