Layer 3 Redundant Protocols

VRRP Settings

Virtual Router Redundancy Protocol (VRRP) can solve the problem with static configuration. VRRP enables a

group of routers to form a single virtual router with a virtual IP address. The LAN clients can then be configured

with the virtual router’s virtual IP address as their default gateway. The virtual router is the combination of a

group of routers, and is also known as a VRRP group.

Virtual IP L3 switches / routers in the same VRRP group must be set to

the same virtual IP address as the VRRP ID. This virtual IP

address must belong to the same address range as the real IP

address of the interface.

0.0.0.0

Virtual Router ID Virtual Router ID is used to assign a VRRP group. The L3

switches / routers, which operate as master / backup, should

have the same ID. Moxa L3 switches / routers support one

virtual router ID for each interface. IDs can range from 1 to

255.

Priority Determines priority in a VRRP group. The priority value range is

1 to 255 and the 255 is the highest priority. If several L3

switches / routers have the same priority, the router with

higher IP address has

the higher priority. The usable range is “1

to 255”.

100

Preemption Mode Determines whether a backup L3 switch / router will take the

authority of master or not.

Enabled

Track Interface The Track Interface is used to track specific interface within the

router that can change the status of the virtual router for a

VRRP Group. For example, the WAN interface can be tracked

and if the link is down, the other backup router will

become the

new master of the VRRP group.
