You should always use a loopback interface (logical interface) to be your router id not a physical interface. So make sure you have a loopback interface with IP address assign to it. Then that will become your router ID and if you change any Physical interface BGP will not be effected.
I need remove a interface, old connection sing bgp. however, I found its ip address act as bgp router-id currently.
I get advice that if I remove the interface configuration, what happend
with the bgp router-id? will it change immediatly? if so, will it case
a reboot? or bgp connection reset?
Any comment will be apprecaited
Thanks in advance
Changing your router-id will be effective after you reset your BGP connections and the best practice recommends that RID with the "bgp router-id" command and that this address be associated with a loopback interface address.
