IP Address
Every logical interface is assigned its own IP address, or range of addresses, that is
unique on the LAN. The VRRP interface must be assigned the IP address that serves
as the default static gateway for other devices on the LAN.
For example, assume that the gateway IP address is 192.168.100.254. If the default
logical interface (0:0) is to be the VRRP interface, it is assigned the gateway address.
Another logical interface (0:1) is defined to be the management interface and is
assigned another IP address.
NOTE:
You must assign the same IP address to the VRRP interface in the master router and
in every router that is to serve as its backup. For example, if the VRRP interface is
assigned IP address 192.168.100.254 in router A, the VRRP interface in every
backup router for router A must be assigned IP address 192.168.100.254.
RIP Processing
Routers using VRRP do not need RIP protocol processing to discover routes. (See
“RIP Controls” on page 6-4.) You may, therefore, turn off RIP processing using these
commands:
-> eth ip options txrip off
-> eth ip options rxrip off
Defining the VRID
The next step is to define a virtual router ID, or VRID, and associate it with the logical
Ethernet interface that is to be the VRRP interface. (The management interface is not
assigned a VRID).
For example, the following command assigns the VRID 7 to the logical interface 0:1
that is to serve as the VRRP interface.
-> eth ip vrid 7 0:1
-> eth ip addr 192.168.100.254 255.255.255.0
-> eth add 0:1
-> eth ip addr 192.168.254.253 255.255.255.0 0:1
