Bird/iBGP

31 Jul 2009

      Hello,

our bird is now connected to our upstream provider.

I see the following behaviour:

Bird gets 287952 prefixes from its upstream router, but does not
redistribute those routes to its direct iBGP neighbours. The neighbours
are: Quagga 0.99.13 and OpenBGPD-current (cvs update from today)

Quagga does redistribute its externaly learnt routes via iBGP.

What am i missing?

Here my configuration:

----------------------------------------------------------------------------------
# Configure logging
log syslog { debug, trace, info, remote, warning, error, auth, fatal, bug };
#log stderr all;
#log "bird.log" all;

# Override router ID
router id x.x.x.8;

protocol direct {
}

protocol kernel {
	persist;		# Don't remove routes on bird shutdown
	scan time 20;		# Scan kernel routing table every 20 seconds
	export all;		# Default is export none
}

protocol device {
	scan time 10;		# Scan interfaces every 10 seconds
}

	route x.x.x.0:255.255.255.0 via x.x.x.4;
}

filter ospfout {
	if net ~ x.x.x.0/24 then accept;
	else reject;
}

	else reject;
}
