VRRP

Virtual Routing Redundancy Protocol (VRRP) is a function on the Switch that dynamically assigns responsibility for a

virtual router to one of the VRRP routers on a LAN. The VRRP router that controls the IP address associated with a virtual

alled the Master, and will forward packets sent to this IP address. This will allow any Virtual Router IP address

N to be used as the default first hop router by end hosts. Utilizing VRRP, the administrator can achieve a higher

routers on

his protocol to function optimally.

To enable VRRP globally on the Switch, click Configuration > Layer 3 IP Networking > VRRP > VRRP

on the LA

available default path cost without needing to configure every end host for dynamic routing or routing discovery protocols.

Statically configured default routes on the LAN are prone to a single point of failure. VRRP is designed to eliminate these

failures by setting an election protocol that will assign a responsibility for a virtual router to one of the VRRP

the LAN. When a virtual router fails, the election protocol will select a virtual router with the highest priority to be the

Master router on the LAN. This retains the link and the connection is kept alive, regardless of the point of failure.

To configure VRRP for virtual routers on the Switch, an IP interface must be present on the system and it must be a part of

a VLAN. VRRP IP interfaces may be assigned to every VLAN, and therefore IP interface, on the Switch. VRRP routers

within the same VRRP group must be consistent in configuration settings for t
