Chapter 10 Configuring Networking Protocols
Basic IP Routing Protocol Configuration
BGP
To configure the BGP protocol, perform the following procedure, beginning in global configuration
mode:
Enabling IP Routing
By default, IP routing is enabled. Beginning in privileged EXEC mode, follow these steps to enable IP
routing:
Use the no ip routing global configuration command to disable routing.
This example shows how to enable IP routing using RIP as the routing protocol:
Router# configure terminal
Router(config)# ip routing
Router(config)# router rip
Router(config-router)# network 10.0.0.0
Router(config-router)# end
Command Purpose
Step 1
Router(config)# router bgp
autonomous-system-number
Defines BGP as the IP routing protocol.
The autonomous system number is the autonomous
system to which this ML-Series card belongs.
Step 2
Router(config-router) # network
net-number
Defines the directly connected networks that run
BGP.
The network number is the number of the network
that is advertised by this ML-Series card.
Step 3
Router(config-router)# exit
Returns to global configuration mode.
Command Purpose
Step 1
Router# configure terminal
Enters global configuration mode.
Step 2
Router(config)# ip routing
Enables IP routing (default).
Step 3
Router(config)# router
ip_routing_protocol
Specifies an IP routing protocol. This step might include
other commands, such as specifying the networks to route
with the network (RIP) router configuration command. For
information about specific protocols, refer to sections later
in this chapter and to the Cisco IOS IP and IP Routing
Configuration Guide.
Step 4
Router(config-router)# end
Returns to privileged EXEC mode.
Step 5
Router(config)# show running-config
Verifies your entries.
Step 6
Router(config)# copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
