The action to take on the extended community list if this route map matches the route. Note that if the action is AMB_BGP_SET_SPECIFIC or AMB_BGP_REMOVE_ALL_AND_SET, the bgpRouteMapSeExtComm field should only contain a single specific extended community value, which will be added to the route. If the action is AMB_BGP_REMOVE_SPECIFIC, then the bgpRouteMapSeExtComm field must contain a regular expression string that matches the extended community (or communities) to be removed. The possible action values are: AMB_BGP_NONE - Ignore the value of bgpRouteMapSeExtComm and do nothing. AMB_BGP_REMOVE_ALL - Ignore the value of bgpRouteMapSeExtComm and remove all extended communities from the route. AMB_BGP_REMOVE_SPECIFIC - Remove from the route all extended communities that match the regular expression in bgpRouteMapSeExtComm. AMB_BGP_SET_SPECIFIC - Append the extended community in bgpRouteMapSeExtComm to the extended communities list. AMB_BGP_REMOVE_ALL_AND_SET - Remove all extended communities from the route and replace them with the extended community in bgpRouteMapSeExtComm. Note that you can delete or add a list of extended communities using the bgpRouteMapSeXCommListDel and bgpRouteMapSeXCommListAdd fields.
