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.

 - Fixes pair ~ pair set matching.
 - Documentation updates.

Ondrej Zajicek 41677025ee Changes 'ignore communities' to 'interpret communities'. 2010-01-28 15:59:18 +01:00
Ondrej Zajicek 6cb8f742f1 Better handling of well-known communities. 
Process well-known communities before the export filter (old behavior is
to process these attributes after, which does not allow to send route
with such community) and just for routes received from other BGP
protocols. Also fixes a bug in next_hop check.

Martin Mares 7294f68b3b path metric' and disable after error' are switches, not numeric clauses. 2000-05-29 22:08:04 +00:00
Martin Mares e3f2d5fce3 Cleanup of configuration. 
o  Use `expr' instead of `NUM' and `ipa' instead of `IPA',
   so that defined symbols work everywhere.
o  `define' now accepts both numbers and IP addresses.
o  Renamed `ipa' in filters to `fipa'.

Pavel, please update filters to accept define'd symbols as well.
