instance must first be created using the command

The bgp router-id command allows an IPv4 address to be specified for use as the BGP router ID. If no
IPv4 address is configured at BGP startup, it uses the highest IPv4 address configured on a loopback
interface. If no loopback interfaces are configured, it uses the highest IPv4 address configured on any
interface that is active. If the specified router ID is changed, existing sessions with BGP neighbors are
reset.
