Pathvector can generate a keepalived configuration for VRRP. Define instances under the global vrrp key; the config is written to the keepalived-config file (default /etc/keepalived.conf) on each pathvector generate. See VRRPInstance for all options.
keepalived-config: /etc/keepalived/keepalived.conf
vrrp:
lan:
state: primary # or backup
interface: eth0 # Interface that sends and receives VRRP advertisements
vrid: 1
priority: 255
vips:
- 192.0.2.1/24
- 2001:db8::1/64
IPv4 VIPs are rendered in keepalived's virtual_ipaddress block and IPv6 VIPs in virtual_ipaddress_excluded.
Binding VIPs to a different interface
By default, keepalived adds the virtual IPs to the same interface that sends VRRP packets (interface). Set vip-interface to add them to a different interface instead, for example to run VRRP over a dedicated link or VLAN while the VIPs live on a loopback or customer-facing interface:
vrrp:
lan:
state: primary
interface: eth0 # VRRP advertisements are sent on eth0
vip-interface: eth1 # VIPs are added to eth1
vrid: 1
priority: 255
vips:
- 192.0.2.1/24
- 2001:db8::1/64
This renders each VIP with keepalived's dev keyword:
vrrp_instance VRRPlan {
state MASTER
interface eth0
virtual_router_id 1
priority 255
advert_int 1
virtual_ipaddress {
192.0.2.1/24 dev eth1
}
virtual_ipaddress_excluded {
2001:db8::1/64 dev eth1
}
}
vip-interface applies to all VIPs in the instance. Create separate instances if VIPs need to be bound to different interfaces.
