The default BGP additional path capability for I-BGP sessions. This can be overridden at the BGP peer AFI/SAFI or peer group AFI/SAFI level (bgpPeerAfiSafiAddPathCapCfg or bgpPeergrAfiSafiAddPathCapCfg). BGP additional path capability is never enabled by default for E-BGP sessions - instead it should be configured for specific E-BGP peers at the peer AFI/SAFI or peer group AFI/SAFI level. This field applies to all configured I-BGP peers including confederation peers in different member ASs. It does not apply to unconfigured peers that are accepted because bgpNmListenAcceptAll is true. Valid values are: - AMB_BGP_ADD_PATH_SR_DISABLE Disable sending and receiving additional BGP paths - AMB_BGP_ADD_PATH_SR_RECEIVE Receive but do not send additional BGP paths - AMB_BGP_ADD_PATH_SR_SEND Send but do not receive additional BGP paths - AMB_BGP_ADD_PATH_SR_BOTH Send and receive additional BGP paths. Any update to this object will take effect the next time that the peer session reactivates.
