Separating OSPF into Multiple Instances

Hello!  

I was curious if anyone has leveraged the ability to separate OSPF into different instances on the same gateway.  

Questions:

1) What was the reason for it?

2) Did it pan out?

3) Any gotchas or interesting things that happened after implementing?

Looking at doing this for a client and wanted to gather some insight before recommending it. 

 

Cheers!

I know one customer had to do this while ago because of the other side, but though it worked, I cant remember exactly all we had to do, so will check if I can find any notes about it tomorrow.

Did it pan out? Yes, we did make it work. Any gotchas or interesting things after it was done? Um, actually yes lol. I vaguely recall specific traffic was getting dropped and it had to do with IPS, but this was back in R80.10, so lots has changed since then.

Thanks for the insight!  After talking to some of my colleagues, I'm thinking unless there is a specific reason to separate things into multiple instances, I'll be recommending to my client to just leave well enough alone.  If it ain't broke....

So sorry man, totally forgot to check on this for you, my sincere apologies : - (. Just went through my notes and I found that it was Cisco ASR in question and it also involved ospf enabled loopback interface, so Im fairly sure that is why all this was done.

I agree with you, why fix it if it aint broke 🙂

Cheers and again, accept my apologies for not updating you sooner.

Best,

Andy
