Cisco IOS IP Configuration Guide, Volume 2 of 3: Routing Protocols, Release 12.2.
Monitoring and Maintaining EIGRP
You can delete neighbors from the neighbor table. You can also display various EIGRP routing statistics.
Table 38-8 lists the privileged EXEC commands for deleting neighbors and displaying statistics. For
explanations of fields in the resulting display, see the Cisco IOS IP Command Reference, Volume 2 of 3:
Routing Protocols, Release 12.2.
Configuring BGP
The Border Gateway Protocol (BGP) is an exterior gateway protocol used to set up an interdomain
routing system that guarantees the loop-free exchange of routing information between autonomous
systems. Autonomous systems are made up of routers that operate under the same administration and
that run Interior Gateway Protocols (IGPs), such as RIP or OSPF, within their boundaries and that
interconnect by using an Exterior Gateway Protocol (EGP). BGP Version 4 is the standard EGP for
interdomain routing in the Internet. The protocol is defined in RFCs 1163, 1267, and 1771. You can find
detailed information about BGP in Internet Routing Architectures, published by Cisco Press, and in the
“Configuring BGP” chapter in the Cisco IP and IP Routing Configuration Guide.
