4.6.6 VRRP

The Virtual Router Redundancy Protocol (VRRP) is designed to eliminate the

single point of failure inherent in the static default routed environment. VRRP

speciﬁes an election protocol that dynamically assigns responsibility for a virtual

router to one of the VRRP routers on a LAN. The VRRP router controlling the IP

address(es) associated with a virtual router is called the Master, and forwards

packets sent to these IP addresses. The election process provides dynamic fail-

over in the forwarding responsibility should the Master become unavailable. Any

of the virtual routerʼs IP addresses on a LAN can then be used as the default

first hop router by end-hosts. The advantage gained from using VRRP is a

higher availability default path without requiring conﬁguration of dynamic routing

or router discovery protocols on every end-host.

Virtual ID:

Virtual router ID, range 1 to 255. One virtual router ID can be

used as the default gateway for one or several vlan
