Configuring a Virtual IP Address
To configure a virtual IP address, use the following commands.
1. Configure a VRRP group.
INTERFACE mode
vrrp-group vrrp-id
The VRID range is from 1 to 255.
2. Configure virtual IP addresses for this VRID.
INTERFACE -VRID mode
virtual-address ip-address1 [...ip-address12]
The range is up to 12 addresses.
The following example shows how to configure a virtual IP address.
The following example shows how to verify a virtual IP address configuration.
NOTE: In the following example, the primary IP address and the virtual IP addresses are on the same subnet.
The following example shows the same VRRP group (VRID 111) configured on multiple interfaces on different subnets.
When the VRRP process completes its initialization, the State field contains either Master or Backup.
Setting VRRP Group (Virtual Router) Priority
Setting a virtual router priority to 255 ensures that router is the “owner” virtual router for the VRRP group. VRRP elects the
MASTER router by choosing the router with the highest priority.
The default priority for a virtual router is 100. The higher the number, the higher the priority. If the MASTER router fails, VRRP
begins the election process to choose a new MASTER router based on the next-highest priority.
If two routers in a VRRP group come up at the same time and have the same priority value, the interface’s physical IP addresses
are used as tie-breakers to decide which is MASTER. The router with the higher IP address becomes MASTER.
To configure the VRRP group’s priority, use the following command.
● Configure the priority for the VRRP group.
INTERFACE -VRID mode
priority priority
The range is from 1 to 255.
The default is 100.
To verify the VRRP group priority, use the show vrrp command.
Configuring VRRP Authentication
Simple authentication of VRRP packets ensures that only trusted routers participate in VRRP processes.
When you enable authentication, Dell EMC Networking OS includes the password in its VRRP transmission. The receiving router
uses that password to verify the transmission.
NOTE:
You must configure all virtual routers in the VRRP group the same: you must enable authentication with the same
password or authentication is disabled.
NOTE: Authentication for VRRPv3 is not supported.
To configure simple authentication, use the following command.
● Configure a simple text password.
INTERFACE-VRID mode
authentication-type simple [encryption-type] password
Parameters:
○ encryption-type: 0 indicates unencrypted; 7 indicates encrypted.
