Ondrej Zajicek 69a8259c5e Allows sticky link-local neighbors. 
Allows using NEF_STICKY neighbors with link-local addresses. This is

Ondrej Zajicek e81b440f68 Fix configure to enable warnings and fix most of them. 2010-02-21 14:34:53 +01:00
Ondrej Filip 89534cdae5 'rr client id' is not expression but ID (like router id). 2010-02-20 21:14:02 +01:00
Ondrej Zajicek dca75fd7c2 Removes phantom protocol from the pipe design. 
It seems that by adding one pipe-specific exception to route
announcement code and by adding one argument to rt_notify() callback i
could completely eliminate the need for the phantom protocol instance
and therefore make the code more straightforward. It will also fix some
minor bugs (like ignoring debug flag changes from the command line).

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.
