Multi-process OSPF redistribution and failover

[Jesse Hottle]

Hello,

I have two ospf processes running on a single 3570 edge router that has a dedicated transport circuit back to our network core. We are adding an additional "transport" only circuit into a new location that is also apart of the second ospf process backbone which will connect back to our core. There will also be a 3750 for this new circuit termination.

Currently we are only redistributing ospf process 2 into ospf process 1 (1 = core backbone).

#router ospf 1

#redistribute ospf 2 subnet

We have no need to have ospf process 1 redistributed into the process 2 tables. That being said, when we add an additional transport ciruit, or path back to our core backbone, will this configuration present any issues with the redistribution process and failover.. I have attached a brief diagram.

Hi,

What is the purpose of having two different OSPF process IDs?  Process IDs are just numbers and don't provide route table separation.

Our backbone area 0 is getting pretty big from a number of routers standpoint and a number of route standpoint. Please we need to do inter-area summarization within each area 0 process.
