Configuring IP Unicast Routing
Table 30-12 IP BGP Clear and Show Commands (continued)
Command
show ip bgp neighbors [address]
show ip bgp neighbors [address] [advertised-routes |
dampened-routes | flap-statistics | paths
regular-expression | received-routes | routes]
show ip bgp paths
show ip bgp peer-group [tag] [summary]
show ip bgp summary
You can also enable the logging of messages generated when a BGP neighbor resets, comes up, or goes
down by using the bgp log-neighbor changes router configuration command.
Configuring Protocol-Independent Features
This section describes how to configure IP routing protocol-independent features. These features are
available on switches running the SMI or the EMI; except that with the SMI, protocol-related features
are available only for RIP. For a complete description of the IP routing protocol-independent commands
in this chapter, refer to the "IP Routing Protocol-Independent Commands" chapter of the Cisco IOS IP
and IP Routing Command Reference for Release 12.1.

Configuring Cisco Express Forwarding
Cisco Express Forwarding (CEF) is a Layer 3 IP switching technology used to optimize network
performance. CEF implements an advanced IP look-up and forwarding algorithm to deliver maximum
Layer 3 switching performance. CEF is less CPU-intensive than fast switching route caching, allowing
more CPU processing power to be dedicated to packet forwarding. In dynamic networks, fast switching
cache entries are frequently invalidated because of routing changes, which can cause traffic to be process
switched using the routing table, instead of fast switched using the route cache. CEF use the Forwarding
Information Base (FIB) lookup table to perform destination-based switching of IP packets.
