[bgpd] Add support for AS_PATHLIMIT / draft-ietf-idr-as-pathlimit
2007-07-31 Paul Jakma <paul.jakma@sun.com> * (general) Support for draft-ietf-idr-as-pathlimit-03. * bgp_attr.h: (struct attr) Add pathlimit struct bgp_attr.c: (attr_str) Add BGP_ATTR_AS_PATHLIMIT string. (attrhash_key_make) tally pathlimit too (attrhash_cmp) cmp pathlimit attr (bgp_attr_aspathlimit) New, parse AS_PATHLIMIT attr. (bgp_attr_parse) ditto (bgp_packet_attribute) Write out AS_PATHLIMIT when set (bgp_dump_routes_attr) ditto * bgp_route.h: (struct bgp_static) Add TTL field * bgp_route.c: (bgp_announce_check) Drop paths that are over their hop-count TTL before sending via EBGP. Mangle ASN in pathlimit for confeds/private as best we can. (bgp_static_update_{rsclient,main}) Add any configure pathlimit information. (bgp_pathlimit_update_parents) New, update atomic-aggr setting for parents of an aspathlimit'ed static. (bgp_static_set) Add TTL argument, for all the 'bgp network' commands. Call previous for TTL changed statics. (bgp_static_unset) Call pathlimit_update_parents. (various bgp network commands) Add 'pathlimit <0-255>' qualifier to all the various forms, bar route-map - which can set ttl itself. * bgp_routemap.c: (general) Add support for 'set pathlimit ttl' and 'match pathlimit as'. * doc/bgpd.texi: Document 'network ... pathlimit <ttl>'
