Configure Vrrp Authentication - Dell Force10 C150 Configuration Manual

Configure VRRP Authentication

Note: Authentication is not available for IPv6 VRRP.
Simple authentication of VRRP packets ensures that only trusted routers participate in VRRP processes.
When authentication is enabled, FTOS includes the password in its VRRP transmission, and the receiving
router uses that password to verify the transmission.
Note: All virtual routers in the VRRP group must be configured the same: authentication must be enabled
with the same password or authentication is disabled.
Configure simple authentication with the following command in VRRP configuration mode:
Task
Configure a simple text password.
Note: As shown in
encrypted form in show running-config (EXEC Privilege) and show config (INTERFACE) command
output. To display the VRRP authentication password (as well as all other FTOS passwords) in clear text
in show command output, you must enter the no service password-encryption (CONFIGURATION)
command. To remove the currently configured VRRP authentication password, enter the no
authentication-type simple [encryption-type] password command.
