OSPF FR adjacency question
They are all correct. I’m sure the lab task wording will drive you toward one or the other option. As long as you know all the ways of making it working you are fine. Sabrina

Hello all, I’m sure this question comes up all the time, but i’ve had a quick look through the archive and could find a previous posting. I’d like your opinion on the following scenario (hub & spoke over FR, single subnet): Hub / / Spoke1 Spoke2
- Hub has point-to-multipoint interface (in both ospf and FR and has FR broadcast to spokes) - Spokes have point-to-point interfaces (in both ospf and FR and has interface-dlci to hub)
By default this configuration will not build an adjacency because of different hello timers. Which of the following solutions (or others if you have them) do you think is the “prefered” way to set up OSPF adjancencies in this scenario?
1. Change hello time on both spokes to 30 secs. 2. Change hello time on hub to 10 secs. 3. Change the ospf network type on spokes to point-to-multipoint
Thanks,
Peter
