Configured policy for origination of default routes. The value of bgpPeerAfiSafiOrigDefaultRtMap is only examined if bgpPeerAfiSafiOrigDefault is 'true'. It identifies a route map consisting of all rows in the bgpRouteMapTable with bgpRouteMapIndex set to bgpPeerAfiSafiOrigDefaultRtMap. The route map has two purposes. - The match clauses are used for conditional advertisement of the default route. A default route is only originated for an address family if bgpPeerAfiSafiOrigDefault is 'true' and if there is at least one route in the loc-RIB matching the route map. - The set clauses of the route map determine the attributes of the originated default route. Note that route maps may consist of multiple bgpRouteMapTable entries. These bgpRouteMapTable entries can be configured to match a specific address family. Any such bgpRouteMapTable entry that does not match the address family for this bgpPeerAfiSafiTable entry is ignored. These route maps should be configured as follows. - To restrict a route map to a particular AFI/SAFI, specify bgpRouteMapMaAfi and bgpRouteMapMaSafi. - Each route map should specify an IP prefix list to match on. This is not mandated by DC-BGP, but other types of matches may have a performance impact. - Each IP prefix match is assumed to be an exact match. In other words, DC-BGP treats each bgpIpPreTable entry as having bgpIpPreLe = bgpIpPreLen, and bgpIpPreGe = 0. The peer may be configured to ignore this field and instead obtain the value from a peer-group as explained in the table description.
