Configuring Basic BGP
Router1(config)#route-map ANEXAMPLE permit 10
Router1(config-rou)#match ip address 1
Router1(config-rou)#set metric 25
Router1(config-rou)#exit
Router1(config)#route-map ANEXAMPLE permit 20
Router1(config-rou)#exit
Router1(config)#access-list 1 permit 172.16.0.0
0.0.255.255
Router1(config)#^Z
Router1#
router bgp 63001
network 172.16.0.0
neighbor 172.16.1.1 remote-as 59000
neighbor 172.16.2.1 route-map ANEXAMPLE out
!
ip classless
access-list 1 permit 172.16.0.0 0.0.255.255
route-map ANEXAMPLE permit 10
match ip address 1
set metric 25

route-map ANEXAMPLE permit 20

This configuration sets a MED of 25 for all networks belonging to
172.16.0.0. ASN 59000 will use this value. Lower MED values are pre-
ferred. The second permit statement of the route-map ANEXAMPLE permits
all other networks to be advertised but does not assign a MED value. We'll
discuss route maps in more detail in Chapter 9.
Clearing BGP Routes
The BGP configurations can easily be removed from the router using the
clear ip bgp
command. Let's look at the command and the available syn-
taxes that are used in Privileged EXEC mode, and then we'll explain each
syntax:
clear ip bgp *|address [soft[in|out]
