Added "src" to struct nexthop. Added preferred src arg to nexthop_ipv4_add and rib_add_ipv4. * zebra/rt_netlink.c: (netlink_routing_table) set preferred source on netlink messages. (netlink_route_change) ditto (netlink_route_multipath) ditto. * zebra/rtread_getmsg.c: (handle_route_entry) added (NULL) src to rib_add_ipv4() call. * zebra/rtread_proc.c: (proc_route_read) ditto * zebra/zebra_rib.c: (nexthop_ipv4_add) add src argument. (nexthop_ipv4_ifindex_add) ditto (rib_add_ipv4) ditto (nexthop_active_check) Add route-map processing. * zebra/zebra_routemap.c: new file for zebra route-map commands. * zebra/zebra_vty.c: (ip_protocol_cmd) Apply route-map to protocol (vty_show_ip_route_detail) added "src" printing (vty_show_ip_route) ditto (show_ip_protocol_cmd) new command, list routemaps. (config_write_protocol) write out routemap protocl config. (zebra_vty_init) Install the new routemap protocol commands. * zebra/zserv.c: (zread_ipv4_add) added (NULL) src arg (zebra_init) init zebra route-maps. * zebra/zserv.h: add zebra_route_map_init --- doc/ChangeLog | 5 +++++ doc/main.texi | 53 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 58 insertions(+) (limited to 'doc') diff --git a/doc/ChangeLog b/doc/ChangeLog index 586852c6..b8c81e74 100644 --- a/doc/ChangeLog +++ b/doc/ChangeLog @@ -1,3 +1,8 @@ +2007-05-01 David L Stevens + + * main.texi: added route-map, prefix-list, ip protocol + and set src documentation + 2007-04-30 Andrew J.
