The address type of the bgpPeergrAddrSource field. Setting this field to the default value means that bgpPeergrAddrSource is unspecified. This field is ignored for peers identified only by interface (bgpPeerLocalAddr and bgpPeerRemoteAddr are both zero). An AMB_INETWK_ADDR_TYPE_IPV6 must always be global. 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 row_status ACTIVE, the change will only take effect after the peer has been cycled row_status NOT_IN_SERVICE and then ACTIVE, thus forcing the peer session to be recreated. In this case, until the peer is set row_status NOT_IN_SERVICE, the peer will be marked as out of date (as reported by the config_state field in the AMB_BGP_PEER_STATUS row for the peer).
