Issue 2381: interface based routes not marked "up" when they originate in zebra, redistributed to bgp vrf, then imported to vpn and then imported by another vrf. Routes that are redistributed into BGP from zebra should not get nexthop tracking (the assumption is that the originating protocol is responsible to export or withdraw the route according to its own notion of nexthop status). The vpn-vrf route-leaking code checks the source route sub_type to decide whether to use nexthop tracking on the resulting leaked route. A route that is redistributed from zebra into bgp will have sub_type==BGP_ROUTE_REDISTRIBUTE. If it is leaked to the vpn RIB, the resulting vpn RIB route will have sub_type==BGP_ROUTE_IMPORTED. If THAT vpn route is leaked to another vrf, the original code will examine only the leak-source route sub_type and, since it is not BGP_ROUTE_REDISTRIBUTE, will wrongly try to use nexthop tracking on the new route in the final vrf. This change modifies the leak function to track back up the parent links to the ultimate parent of the leak source route and look at that route's sub_type instead. Signed-off-by: G.

FRRouting is free software that implements and manages various IPv4 and IPv6 routing protocols. Currently FRRouting supports BGP4, BGP4+, OSPFv2, OSPFv3, RIPv1, RIPv2, RIPng, IS-IS, PIM-SM/MSDP, LDP and Babel as well as very early support for EIGRP and NHRP. See doc/user/bugs.rst for information on how to report bugs. See doc/developer/workflow.rst for information on contributing. See the file COPYING for copying conditions.
