This value indicates whether or not the peers in this peer group are members of the same confederation that this router is in. This field can only be set to true if the field bgpRmEntConfederationId is non-zero. Note that the value should be set to true even if the peers in this peer group are in the same member AS that this router is in. Member AS numbers are kept internal to the confederation, so it is possible for a member AS number to be the same as the AS number of a neighbor outside the confederation, and so it is not possible to determine whether a peer is in this confederation just by examining the peer's AS number. The value of this field resolves any ambiguity. This field can be changed at any time. However, if a peer is configured to use the peer group field and the field is changed while the peer is active, depending on the setting of the bgpPeergrResetPeerOnCfgChange field, the peer session may either be immediately reset, or the configuration change is not applied until the peer session is restarted.
