Is it good practice to use same router id for bird and bird6 ?

[olivier a]

let's 192.168.1.1 is my router Wan IP. One single physical router running
bird and bird6.

Solution 1 :
bird router id = 192.168.1.1
bird6 router id = 192.168.1.1

Solution 2 :
bird router id = 192.168.1.1
bird6 router id = 127.0.0.1

Is that what you're advising ?
What are the benefits of using IPv4 loopback as bird6 router id ??!
:-)
