The master periodically sends VRRP Advertisement packets in the VRRP group to advertise its configurations such as the priority. 

Even if the VRRP device is the IP address owner, it still needs to participate in the election and does not directly transition to the Master state when receiving a message indicating that the interface goes Up.

When advertising a locally originated route to an IBGP peer, a BGP device sets the next hop address to the IP address of its interface connected to the peer.

When advertising a non-labeled route received from an EBGP peer to an IBGP peer, a BGP device changes the next hop address to the IP address of its interface connected to the IBGP peer.

When advertising a route to an EBGP peer, a BGP device sets the next hop address to the IP address of its interface connected to the peer. 

A BGP device does not change the next hop address of a route if the route is received from an IBGP peer and is to be sent to another IBGP peer.
