Hello David, I tried the following, pretty straightforward setup. I'v a full mesh iBGP running on 3 lab routers and OSPF between them (simple triangle).
The IP to be checked is on a /30 in between R1 & R2, when this go down, I want R1 to stop announcing the ip route (should disappear on R3). The tag 1755 is to force the route to be advertised through iBGP and not OSPF. If the IP to be checked goes down, I can see that the SLA Monitor status goes to down but yet, R1 keep advertising the route. Any idea why? ip sla monitor 1 type echo protocol ipIcmpEcho 10.0.1.2 timeout 800 frequency 2 ! ip sla monitor schedule 1 life forever start-time now track 100 rtr 1 reachability ip route 17.4.240.40 255.255.255.240 Se0/1:0 tag 1755 track 100 Thanks in advance :) Henry-Nicolas Tourneur. -----Original Message----- From: David Prall [mailto:[email protected]] Sent: jeudi 24 novembre 2011 19:20 To: 'Henry-Nicolas Tourneur'; [email protected] Subject: RE: [c-nsp] Conditionnal routing based on OSPF / IP SLA You can do this with track objects and static routing, then redistribute the static into ospf. You could use a conditional route-map like they do in the example for default as well. But I think putting a static in and redistributing it will be much easier.

Currently, I found this tutorial: http://hackingcisco.blogspot.com/2011/03/lab-33-ospf-conditional-default-rou ting.html But it's only for "default-information", I would need this for a particular route. Does anybody have an idea how to do this? Thanks and regards, Henry-Nicolas Tourneur. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
