(at Technical University of Madrid as part of Euro6ix Project)
Enhanced Route Server functionality and Route-Maps:
* bgpd/bgpd.h: Modified 'struct peer' and 'struct bgp_filter' to
support rs-clients. A 'struct bgp_table *rib' has been added to the
first (to mantain a separated RIB for each rs-client) and two new
route-maps have been added to the last (for import/export policies).
Added the following #defines: RMAP_{IN|OUT|IMPORT|EXPORT|MAX},
PEER_RMAP_TYPE_{IMPORT|EXPORT} and BGP_CLEAR_SOFT_RSCLIENT.
* bgpd/bgpd.c: Modified the functions that create/delete/etc peers in
order to consider the new fields included in 'struct peer' for
supporting rs-clients, i.e. the import/export route-maps and the
'struct bgp_table'.
* bgpd/bgp_route.{ch}: Modified several functions related with
receiving/sending announces in order to support the new Route Server
capabilities.
Function 'bgp_process' has been reorganized, creating an auxiliar
function for best path selection ('bgp_best_selection').
Modified 'bgp_show' and 'bgp_show_route' for displaying information
about any RIB (and not only the main bgp RIB).
Added commands for displaying information about RS-clients RIBs:
'show bgp rsclient (A.B.C.D|X:X::X:X)', 'show bgp rsclient
(A.B.C.D|X:X::X:X) X:X::X:X/M', etc
* bgpd/bgp_table.{ch}: The structure 'struct bgp_table' now has two
new fields: type (which can take the values BGP_TABLE_{MAIN|RSCLIENT})
and 'void *owner' which points to 'struct bgp' or 'struct peer' which
owns the table.
When creating a new bgp_table by default 'type=BGP_TABLE_MAIN' is set.
* bgpd/bgp_vty.c: The commands 'neighbor ... route-server-client' and
'no neighbor ... route-server-client' now not only set/unset the flag
PEER_FLAG_RSERVER_CLIENT, but they create/destroy the 'struct
bgp_table' of the peer. Special actions are taken for peer_groups.
Command 'neighbor ... route-map WORD (in|out)' now also supports two
new kinds of route-map: 'import' and 'export'.
Added commands 'clear bgp * rsclient', etc. These commands allow a new
kind of soft_reconfig which affects only the RIB of the specified
RS-client.
Added commands 'show bgp rsclient summary', etc which display a
summary of the rs-clients configured for the corresponding address
family.
* bgpd/bgp_routemap.c: A new match statement is available,
'match peer (A.B.C.D|X:X::X:X)'. This statement can only be used in
import/export route-maps, and it matches when the peer who announces
(when used in an import route-map) or is going to receive (when used
in an export route-map) the route is the same than the one specified
in the statement.
For peer-groups the statement matches if the specified peer is member
of the peer-group.
A special version of the command, 'match peer local', matches with
routes originated by the Route Server (defined with 'network ...',
redistributed routes and default-originate).
* lib/routemap.{ch}: Added a new clause 'call NAME' for use in
route-maps. It jumps into the specified route-map and when it returns
the first route-map ends if the called RM returns DENY_MATCH, or
continues in other case.
