BGP
BGP
To configure the Border Gateway Protocol (BGP), perform the following procedure, beginning in global
configuration mode:
Enabling IP Routing
Beginning in privileged EXEC mode, follow this procedure to enable IP routing:
Note By default, IP routing is already enabled.
Command Purpose
Step 1 Router(config)# router ospf process-ID Defines OSPF as the IP routing protocol.
The process ID identifies a unique OSPF router
process. This number is internal to the ML-Series
card only; the process ID here does not have to
match the process IDs on other routers.
Step 2 Router(config-router)# network
net-address wildcard-mask area area-ID
Assigns an interface to a specific area.
• The net-address is the address of directly
connected networks or subnets.
• The wildcard-mask is an inverse mask that
compares a given address with interface
addressing to determine whether OSPF uses this
interface.
• The area parameter identifies the interface as
belonging to an area.
• The area-ID specifies the area associated with
the network address.
Step 3 Router(config-router)# end Returns to privileged EXEC mode.
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.
