Configuring Ospf; Ospf Overview - Cisco Catalyst 6500 Series Configuration Manual

Configuring OSPF

The following static routes are equal cost routes that direct traffic to three different routers on the outside
interface. The FWSM sends 1/3 of the traffic to each router.
FWSM/contexta(config)# route outside 10.10.10.0 255.255.255.0 192.168.1.1
FWSM/contexta(config)# route outside 10.10.10.0 255.255.255.0 192.168.1.2
FWSM/contexta(config)# route outside 10.10.10.0 255.255.255.0 192.168.1.3

OSPF Overview

Single context mode only
Routed firewall mode only
OSPF uses a link-state algorithm to build and calculate the shortest path to all known destinations. Each
router in an OSPF area contains an identical link-state database, which is a list of each of the router
usable interfaces and reachable neighbors.
