Explanation: vrrp_instance: a virtual router state: master or backup priority: higher priority means that router gets chosen more often authentication: auth_type: can integrate with other ticket based authentication protocols auth_pass: IPv4 sub 8 character passwords, IPv6 allows for longer passwords virtual_ipaddress: the shared IP ranges for the virtual router (can be more than one) Setup Examples Manager: vrrp_instance VI_1 { state MASTER interface eth0 virtual_router_id 51 priority 10 advert_int 1 authentication { auth_type AH auth_pass adguard } virtual_ipaddress { 10.133.7.11/24 } } vrrp_instance VI_2 { state MASTER interface eth0 virtual_router_id 52 priority 10 advert_int 1 authentication { auth_type PASS auth_pass adgaurdhome } virtual_ipaddress { fd48:fb0a:cb3a:b8d4::1234/64 } } Backup: vrrp_instance VI_1 { state BACKUP interface eth0 virtual_router_id 51 priority 1 advert_int 1 authentication { auth_type AH auth_pass adguard } virtual_ipaddress { 10.133.7.11/24 } } vrrp_instance VI_2 { state BACKUP interface eth0 virtual_router_id 52 priority 1 advert_int 1 authentication { auth_type PASS auth_pass adgaurdhome } virtual_ipaddress { fd48:fb0a:cb3a:b8d4::1234/64 } } Notes: Separate setup for IPv4 and IPv6 addresses Can have multiple setup for different interfaces References: redhat arch wiki keepalived documentation
