An router-id is "just" an arbitrary number, where the format is equal to how an IPv4 \
address looks. Even for your IPv6 bird instance.

The router-id can be any random address. (Usually equal to your router's mgmt ipv4 \
address or another ipv4 address on your routers loopback interface.)

router-id: (25[0-5]|2[0-4][\d]|[1-2]?[\d]{1,2})\.(25[0-5]|2[0-4][\d]|[1-2]?[\d]{1,2})\.(25[0-5]|2[0-4][\d]|[1-2]?[\d]{1,2})\.(25[0-5]|2[0-4][\d]|[1-2]?[\d]{1,2}) \
