“interface“ key word is used for Unnumbered IPv6 BGP session .

You don’t have use mask (/24) while configuring neighbor , looks like FRR taking “1.1.1.1/24” as interface name.

Subject: [FROG] What's this 'interface' mean in 'neighbor' configure node ?

Hi all,

I found this is new in FRR compared to QUAGGA, what's this used for ? Why I should config interface first ? Is there some DOC about this ?

# neighbor 1.1.1.1/24
...
  interface                  Enable BGP on interface

# neighbor 1.1.1.1/24 remote-as 5001
% Create the peer-group or interface first or specify "interface" keyword
% if using an unnumbered interface neighbor
