Chapter 14: VRRP Configuration Guide

Note: Since 100 is the default priority, line 9, which sets the priority to 100, is actually unnecessary. It is included for illustration purposes only.

Configuration of Router R3

The following is the configuration file for Router R3 in Figure 19.

1:interface create ip test address-netmask 10.0.0.3/16 port et.1.1

!

2:ip-redundancy create vrrp 1 interface test

3:ip-redundancy create vrrp 2 interface test

4:ip-redundancy create vrrp 3 interface test

!

5:ip-redundancy associate vrrp 1 interface test address 10.0.0.1/16

6:ip-redundancy associate vrrp 2 interface test address 10.0.0.2/16

7:ip-redundancy associate vrrp 3 interface test address 10.0.0.3/16

!

8:ip-redundancy set vrrp 1 interface test priority 100

9:ip-redundancy set vrrp 2 interface test priority 100

!

10:ip-redundancy start vrrp 1 interface test

11:ip-redundancy start vrrp 2 interface test

12:ip-redundancy start vrrp 3 interface test

Lines 8 and 9 set the backup priority for Router R3 at 100 for virtual routers VRID=1 and VRID=2. Since Router R1 has a priority of 200 for backing up virtual router VRID=2, and Router R2 has a priority of 200 for backing up virtual router VRID=1, Router R3 is the secondary Backup for both virtual routers VRID=1 and VRID=2.

The following table shows the priorities for each virtual router configured on Router R3.

Virtual Router
