Proposed Solution From draft-nalawade-idr-mdt-safi: MVPN PE distributes: route for itself in MDT-SAFI family connector attribute on unicast VPN-IPv4 routes, to associate its MDT-SAFI address with those routes (some controversy over coding of this attribute, but not significant to this WG) Now any PE can determine the MDT-SAFI route towards a multicast transmitter at any VPN site. From draft-wijnands-pim-proxy: In case transmitter address is not routable in SP network, specify its BGP NH in the Join message |
