As an example, lets assume an interface (on which VRRP is to be enabled) contains a primary IP<br />

address of 50.1.1.1/24 and a secondary IP address of 60.1.1.1/24. You intend to configure 4 VRRP<br />

groups (VRID 1, VRID 2, VRID 3 and VRID 4) on this interface. VRID 1 should contain virtual<br />

addresses belonging to EITHER subnet 50.1.1.0/24 OR subnet 60.1.1.0/24, but NOT from both<br />

subnets (though <strong>FTOS</strong> allows <strong>the</strong> same). The same rule applies to VRID 2, 3 and 4.<br />

• The virtual IP address assigned in a VRRP group can be <strong>the</strong> same as <strong>the</strong> interface’s primary or<br />

secondary IP address under certain conditions, but <strong>the</strong> virtual IP address cannot be <strong>the</strong> same as any<br />

o<strong>the</strong>r IP address configured on <strong>the</strong> E-<strong>Series</strong>, including <strong>the</strong> virtual IP address <strong>for</strong> a VRRP group on<br />

ano<strong>the</strong>r interface.<br />

• If <strong>the</strong> virtual IP address and <strong>the</strong> interface’s primary/secondary IP address are <strong>the</strong> same, <strong>the</strong> priority on<br />

that VRRP group MUST be set to 255. The interface <strong>the</strong>n becomes <strong>the</strong> OWNER router of <strong>the</strong> VRRP<br />

group and <strong>the</strong> interface’s physical MAC address is changed to that of <strong>the</strong> owner VRRP group’s MAC<br />

address.<br />

• If you have multiple VRRP groups configured on an interface, only one of <strong>the</strong> VRRP groups can<br />

contain <strong>the</strong> interface primary or secondary IP address.<br />

To configure a virtual IP address, use <strong>the</strong>se commands in <strong>the</strong> following sequence in <strong>the</strong> INTERFACE<br />

mode.<br />

Step Command Syntax Command Mode Purpose<br />

1 vrrp-group vrrp-id CONFIG-INT-<br />

(slot/port)<br />

2<br />

virtual-address ip-address1<br />

[...ip-address12]<br />

To view <strong>the</strong> VRRP group configuration, use <strong>the</strong> show config command in <strong>the</strong> VRRP mode or <strong>the</strong> show<br />

vrrp brief command (Figure 311) in <strong>the</strong> EXEC privilege mode.<br />

Figure 311 Command Example: show vrrp brief<br />

<strong>Force10</strong># show vrrp brief<br />

CONFIG-INT-<br />

(slot/port) -VRID<br />

Configure a VRRP group. The range of<br />

vrrp-id is 1 to 255.<br />

Configure up to 12 virtual IP addresses<br />

of virtual routers.<br />
