Configuring a peer group simplifies configuration for neighbors with similar update policies. Once a peer group is created, it can be configured using the same commands for configuring individual BGP neighbors. Each member of the peer group inherits the peer group's update policies unless overridden by explicit configuration of the individual peer. This also makes update calculation more efficient.
All members of a peer group must share identical outbound routing policies—that is, they must have identified distribute lists, filter lists, prefix lists, and route maps applied. They need not have identical settings for default-originate, as this is always processed on a per-peer basis. Inbound update routing policies may vary per peer group member.
