Chapter 38 Configuring IP Unicast Routing
Configuring OSPF
Enter the show ip eigrp neighbor detail privileged EXEC command from the distribution router to
verify the configuration.
Configuring OSPF
This section applies only to the Catalyst Switch Module 3110.
This section briefly describes how to configure Open Shortest Path First (OSPF). For a complete
description of the OSPF commands, see the “OSPF Commands” chapter of the Cisco IOS IP Command
Reference, Volume 2 of 3: Routing Protocols, Release 12.2.
Note OSPF classifies different media into broadcast, nonbroadcast, and point-to-point networks. The switch
supports broadcast (Ethernet, Token Ring, and FDDI) and point-to-point networks (Ethernet interfaces
configured as point-to-point links).
OSPF is an Interior Gateway Protocol (IGP) designed expressly for IP networks, supporting IP
subnetting and tagging of externally derived routing information. OSPF also allows packet
authentication and uses IP multicast when sending and receiving packets.
The Cisco implementation conforms to the OSPF Version 2 specifications with these key features:
• Definition of stub areas is supported.
• Routes learned through any IP routing protocol can be redistributed into another IP routing protocol.
At the intradomain level, OSPF can import routes learned through EIGRP and RIP. OSPF routes can
also be exported into RIP.
• Plain text and MD5 authentication among neighboring routers within an area is supported.
• Configurable routing interface parameters include interface output cost, retransmission interval,
interface transmit delay, router priority, router dead and hello intervals, and authentication key.
• Virtual links are supported.
• Not-so-stubby-areas (NSSAs) per RFC 1587are supported.
Step 4
eigrp stub [receive-only | connected |
static | summary]
Configure a remote router as an EIGRP stub router. The keywords have
these meanings:
• receive-only to set the router as a receive-only neighbor.
• connected to advertise connected routes.
• static to advertise static routes.
• summary to advertise summary routes.
Step 5
end Return to privileged EXEC mode.
Step 6
show ip eigrp neighbor detail Verify that a remote router has been configured as a stub router with
EIGRP. The last line of the output shows the stub status of the remote or
spoke router.
Step 7
copy running-config startup-config (Optional) Save your entries in the configuration file.
