Chapter 9 Configuring IP Routing
Configuring RIP
hostname# show ospf neighbor [ interface-name ] [ neighbor-id ] [ detail ]
•
To display a list of all LSAs requested by a router, enter the following command:
hostname# show ospf request-list neighbor if_name
• To display a list of all LSAs waiting to be resent, enter the following command:
hostname# show ospf retransmission-list neighbor if_name
•
To display a list of all summary address redistribution information configured under an OSPF
process, enter the following command:
hostname#
show ospf
[ process-id ]
summary-address
• To display OSPF-related virtual links information, enter the following command:
hostname# show ospf [ process-id ] virtual-links
Restarting the OSPF Process
To restart an OSPF process, clear redistribution, or counters, enter the following command:
hostname(config)# clear ospf pid { process | redistribution | counters
[ neighbor [ neighbor-interface ] [ neighbor-id ]]}
Configuring RIP
Devices that support RIP send routing-update messages at regular intervals and when the network
topology changes. These RIP packets contain information about the networks that the devices can reach,
as well as the number of routers or gateways that a packet must travel through to reach the destination
address. RIP generates more traffic than OSPF, but is easier to configure.
RIP has advantages over static routes because the initial configuration is simple, and you do not need to
update the configuration when the topology changes. The disadvantage to RIP is that there is more
network and processing overhead than static routing.
The security appliance supports RIP Version 1 and RIP Version 2.
This section describes how to configure RIP. This section includes the following topics:
•
Enabling and Configuring RIP, page 9-19
• Redistributing Routes into the RIP Routing Process, page 9-21
•
Configuring RIP Send/Receive Version on an Interface, page 9-21
• Enabling RIP Authentication, page 9-22
•
Monitoring RIP, page 9-22
Enabling and Configuring RIP
You can only enable one RIP routing process on the security appliance. After you enable the RIP routing
process, you must define the interfaces that will participate in that routing process using the
network
command. By default, the security appliance sends RIP Version 1 updates and accepts RIP Version 1 and
Version 2 updates.
