We have a requirement to configure OSPF & multicast in a sub-interface of Palo Alto for one of our customers. I would like to understand how it would impact the CPU, memory and throughput and the guidelines and best practices to be followed while configuring OSPF. A comparison against having static routes vs processing OSPF routes. Please suggest.
Routing usually doesnt take much overhead. I have ospf running on small boxes without issues. The only thing I can think of would be huge routing tables. So route summarization could come in handy. Also keep track of your areas and remember the OSPF lsa types. The reason I like it is I can add a new site or subnet and everything learns about it automatically.
Agreed. If you aren't dealing with massive route tables, you will probably be just fine. OSPF will save you headache in the long run for sure.
