How many OSPF processes can a 3550 handle?

I need to configure a 3550 for OSPF routing. Because of the design in this case we need to run multiple instances of OSPF. How many instances of OSPF can run on a 3550?

Re: How many OSPF processes can a 3550 handle?

The Cisco IOS software can handle simultaneous operation of up to 30 dynamic IP routing processes. The combination of routing processes on a router consists of the following protocols (with the limits noted):

* Up to 30 IGRP routing processes

* Up to 30 OSPF routing processes

* One RIP routing process

* One IS-IS process

* One BGP routing process
