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.
To activate a VRRP group on an interface, configure at least one virtual IP address for a VRRP group. The virtual IP address is
the IP address of the virtual router and does not require an IP address mask. You can configure up to 10 virtual IP addresses on
a single VRRP group (VRID).
These 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 EMC recommends configuring virtual IP addresses belonging to the same IP subnet for any one VRRP group. An
interface on which you enable VRRP 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 subnet 50.1.1.0/24 or subnet 60.1.1.0/24.
● If you configure multiple VRRP groups on an interface, only one of the VRRP groups can contain the interface primary or
secondary IP address.
NOTE: OS10 does not support configuring the virtual IP address to be the same as the primary or secondary IP address of
the interface. Priority 255 is not supported.
Configure virtual IP address
Configure the virtual IP address — the primary IP address and the virtual IP addresses must be on the same subnet.
1. Configure a VRRP group in INTERFACE mode, from 1 to 255.
vrrp-group vrrp-id
2. Configure virtual IP addresses for this VRRP ID in INTERFACE-VRRP mode. A maximum of 10 IP addresses.
virtual-address ip-address1 [...ip-address10]
Configure virtual IP address
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# no switchport
OS10(conf-if-eth1/1/1)# ip address 10.1.1.1/24
OS10(conf-if-eth1/1/1)# vrrp-group 10
OS10(conf-eth1/1/1-vrid-10)# virtual-address 10.1.1.8
