Hello all, In our OSPF network, when I need to route traffic from our primary link to a backup link, it is taking 20-30 seconds for traffic to shift to the backup link. The method I'm using to do this is by setting the primary link interface in OSPF to "Passive". The second I set this, traffic stops on the primary link but I don't see the traffic shift to the next best cost link for 20-30 seconds. I figured that as soon as I set an interface to Passive, the traffic would shift immediately instead of having that delay.
Is there a better way to take down an OSPF path so traffic shifts to the next lowest cost link immediately instead of having this delay? I know I could change cost on both sides so it shifts seamlessly and I've done this but I'm trying to find out why my way now isn't working right. I'm doing this to upgrade software without customers seeing any downtime but there is and I'm frustrated trying to figure it out.
