can you try running 'sh ip route a.b.c.d', where a.b.c.d is the connected route in question, to an interface that is down? Does it shown down/unavailable? (on zebra telnet port 2601 cli or vtysh) If it shows DOWN/not available, quagga will not redistribute. The problem is that quagga can't know whether tunnel is down or up. if tunnel is up, it passes packets between two endpoints. if its down, it doesn't. i think a solution to this is to provide link detection of tunneling interfaces by providing a heartbeat or keepalives, but thats more work heh. -J On Mon, Jun 14, 2004 at 11:13:05AM +0300, Vlad GALU wrote: > > > Begin forwarded message: > > Date: Mon, 14 Jun 2004 09:03:19 +0100 > From: Bruce M Simpson <bms@spc.org> > To: Vlad GALU <dudu@diaspar.rdsnet.ro> > Subject: Re: A quagga-related issue > > > Hi, > > Unfortunately I'm not a quagga developer, so you might have better luck > getting an answer to your question by posting to -net or asking on the > Quagga forums.
