represented and accessible as new route attributes:

krt_mtu, krt_window, krt_rtt, krt_rttvar, krt_sstresh, krt_cwnd, krt_advmss,
krt_reordering, krt_hoplimit, krt_initcwnd, krt_rto_min, krt_initrwnd,

Ondrej Zajicek 28a10f84cb Some fixes in filter code.
Thanks to Sergey Popovich for original patches.

Ondrej Zajicek 094d2bdb79 Implements ADD-PATH extension for BGP.
Allows to send and receive multiple routes for one network by one BGP
session. Also contains necessary core changes to support this (routing
tables accepting several routes for one network from one protocol).
It needs some more cleanup before merging to the master branch.

Ondrej Zajicek d1e146f2f8 Implements IGP metric comparison for BGP routes. 2010-07-31 01:04:32 +02:00
Ondrej Zajicek cfe34a316e Implements hostcache and recursive next hops.
Hostcache is a structure for monitoring changes in a routing table that
is used for routes with dynamic/recursive next hops. This is needed for
proper iBGP next hop handling.

Ondrej Zajicek d72a0ac239 Fixes serious bug in route attribute handing.
ea_same() sometimes returns true for different route attributes,
which caused that hash table in BGP does not work correctly and
some routes were sent with different attributes.

Ondrej Zajicek aebe06b40c Proper format functions for ORIGINATOR_ID, CLUSTER_LIST 2008-11-08 23:33:22 +01:00
Ondrej Filip 98ac61766d A lot of changes:
- metric is 3 byte long now
	- summary lsa originating
	- more OSPF areas possible
	- virtual links
	- better E1/E2 routes handling
	- some bug fixes..

I have to do:
	- md5 auth (last mandatory item from rfc2328)
	- !!!!DEBUG!!!!! (mainly virtual link system has probably a lot of bugs)
	- 2328 appendig E

Martin Mares 891cec854f Killed one more reference to RTS_RIP_EXT. 2000-05-07 11:27:23 +00:00
Martin Mares ce1da96ee7 Added commands show route protocol <p>' and show route import <p>' which
show the routing table as exported to the protocol given resp. as returned
from its import control hook.

To get handling of filtered extended attributes right (even in the old
`show route where <filter>' command), the get_route_info hook gets an
attribute list and all protocol specific rte attributes are contained
there as temporary ones. Updated RIP to do that.

Added ea_append() which joins two ea_list's.

Martin Mares 3991d84e8f Changed initialization of protocol list -- now we call proto_build() instead
of calling the protocols manually.

Implemented printing of dynamic attributes in `show route all'.

Each protocol can now register its own attribute class (protocol->attr_class,
set to EAP_xxx) and also a callback for naming and formatting of attributes.
The callback can return one of the following results:

	GA_UNKNOWN	Attribute not recognized.
	GA_NAME		Attribute name recognized and put to the buffer,
			generic code should format the value.
	GA_FULL		Both attribute name and value put to the buffer.

Please update protocols generating dynamic attributes to provide
the attr_class and formatting hook.

Martin Mares 221135d6bf Include "lib/string.h" instead of <string.h>. It should give us bzero()
