Microsoft ES4625, ES4649 manual Command Line Interface

4 Command Line Interface

Command Usage

•The interfaces of all routers participating in a virtual router group must be within the same IP subnet.

•The IP address assigned to the virtual router must already be configured on the router that will be the Owner. In other words, the IP address specified in this command must already exist on one, and only one, router in the virtual router group, and the network mask for the virtual router address is derived from the Owner. The Owner will also assume the role of the Master virtual router in the group.

•If you have multiple secondary addresses configured on the current VLAN interface, you can use this command with the secondary keyword to add any secondary address that will be supported by the virtual router.

•VRRP is enabled as soon as this command is entered. If you need to customize any of the other parameters for VRRP such as authentication, priority, or advertisement interval, then first configure these parameters before enabling VRRP.

Example

This example creates VRRP group 1 using the primary interface for VLAN 1 as the VRRP group Owner, and also adds a secondary interface as a member of the group.

Console(config)#interface vlan 1

Console(config-if)#vrrp 1 ip 192.168.1.6

Console(config-if)#vrrp 1 ip 192.168.2.6 secondary

Console(config-if)#
