Indicates whether BGP should originate a default route to the peer for this AFI/SAFI. BGP cannot originate default VPN routes and so bgpPeerAfiSafiOrigDefault cannot be set to 'true' if bgpPeerAfiSafiSafi is 'mplsBgpVpn'. This is because there is no single default route for a VPN address family - there may be one for each VRF. If a default VPN route is required, it should should be redistributed from the corresponding VRF. This ensures that the default VPN route is advertised by BGP along with the associated label, route distinguisher and route targets. Similarly, BGP does not support the allocation of a label for a default route, and so bgpPeerAfiSafiOrigDefault cannot be set to 'true' if bgpPeerAfiSafiSafi is 'labeled'. Default routes are meaningless for L2VPNs, so bgpPeerAfiSafiOrigDefault cannot be set to 'true' if bgpPeerAfiSafiAfi is 'l2vpn'. The origination of default routes may optionally be conditional based on policy. If this is required, then set bgpPeerAfiSafiOrigDefaultRtMap to specify a route map. If no route map is specified (bgpPeerAfiSafiOrigDefaultRtMap is zero), then default route origination is based solely on the setting of bgpPeerAfiSafiOrigDefault. The peer may be configured to ignore this field and instead obtain the value from a peer-group as explained in the table description.
