Prior to release EOS 4.29.1, a statically configured BGP neighbor, listen range or interface peer could reference a single peer group for inheriting configuration parameters. EOS 4.29.1 adds the ability for that peer group to inherit configuration from up to 8 additional “ancestor” peer groups. The term “leaf peer group” is given to the peer group which is directly referenced by the BGP neighbor, listen range or interface peer.
