VIPAbgp - An OCF resource for Pacemaker to announce a VIP via BGP:

1. Uses ryu bgp speaker that should be run at every Pacemaker node with rpc on port 50002.
2. No config rewrite/restart required;
3. Does not assign the VIP to interface itself, but default IPaddr2 resource and collocation constraint can be used for that:

pcs resource create VIPBGP ocf:heartbeat:VIPAbgp ip=192.168.100.100/32

pcs resource create VIPIP ocf:heartbeat:IPaddr2 params ip=192.168.100.100

pcs constraint colocation add VIPBGP with VIPIP

As well as odering constraint will be helpful here:

pcs constraint order VIPIP then VIPBGP kind=Mandatory
