What does this command mean?

Hi guys,

I'm confused with this command

no bgp default ipv4-unicast

What I understood is, it's used to disable IPv4 BGP.

Why would I have to disable it and then configure a router ID.

Can anyone explain please.

What does this command mean?

The bgp default ipv4-unicast command is used to enable the automatic exchange of IPv4 address family prefixes.

IPv4 address family routing information is advertised by default for each BGP routing session configured with the neighbor remote-as command, unless you first configure the no bgp default ipv4-unicast command before configuring the neighbor remote-as command.
