Command Example Display: show config for the Interface Force10(conf-if-gi-1/1)#show conf ! interface GigabitEthernet 1/1 ip address 10.10.10.1/24 ! vrrp-group 111 no shutdown Force10(conf-if-gi-1/1)# Note that the interface has an IP Address and is enabled Assign Virtual IP addresses Virtual routers contain virtual IP addresses configured for that VRRP Group (VRID). A VRRP group does not transmit VRRP packets until you assign the Virtual IP address to the VRRP group. E-Series supports an unlimited total number of VRRP Groups on the router while supporting up to 255 VRRP groups on a single interface (Table 45-1). C-Series supports a total of 128 VRRP groups on the switch with varying number of maximum VRRP groups per interface (Table 45-1). S-Series supports a total of 120 VRRP groups on a switch with FTOS or a total of 20 VRRP groups when using SFTOS. The S-Series supports varying number of maximum VRRP groups per interface (Table 45-1). To activate a VRRP Group on an interface (so that VRRP group starts transmitting VRRP packets), configure at least one Virtual IP address in a VRRP group. The Virtual IP address is the IP address of the Virtual Router and does not require the IP address mask. You can configure up to 12 Virtual IP addresses on a single VRRP Group (VRID). The following rules apply to virtual IP addresses: • The virtual IP addresses must be in the same subnet as the primary or secondary IP addresses configured on the interface. Though a single VRRP group can contain virtual IP addresses belonging to multiple IP subnets configured on the interface, Dell Force10 recommends you configure virtual IP addresses belonging to the same IP subnet for any one VRRP group. For example, an interface (on which VRRP is to be enabled) contains a primary IP address of 50.1.1.1/24 and a secondary IP address of 60.1.1.1/24. The VRRP Group (VRID 1) must contain virtual addresses belonging to either subnet 50.1.1.0/24 or subnet 60.1.1.0/24, but not from both subnets (though FTOS allows the same).
