IP Routing—Configuring RIP, OSPF, BGP, and PBR
Configuring BGP

7. Configure a route map with a new name for the second external neighbor.
Repeat steps 3 through 6. In this second route map, the set of routes that
received the higher metric in the first route map should receive a lower
metric, and one of the sets of routes that received the lower metric in the
first route map should now receive a higher metric.
Configure a separate route map for each neighbor.
If the secondary Internet connections are on different routers, simply
configure the route maps on these routers.
8. Apply the corresponding route map to each neighbor. Move to the config-
uration mode context for the BGP neighbor and enter this command:
Syntax: route-map <mapname> out
For example, your ProCurve Secure Router provides two Internet connections
to your network, which uses variable length subnets in the 10.1.0.0 /16 range.
You should enter these commands to set the multi-exit discriminators:
ProCurve(config)# ip prefix-list MultiExit1 seq 10 permit 10.1.0.0/17 le 24
ProCurve(config)# ip prefix-list MultiExit2 seq 10 permit 10.1.128.0/17 le 24
ProCurve(config)# route-map ISP1 10
ProCurve(config-route-map)# match ip address prefix MultiExit1
ProCurve(config-route-map)# set metric 160
ProCurve(config-route-map)# route-map ISP1 20
ProCurve(config-route-map)# match ip address prefix MultiExit2
ProCurve(config-route-map)# set metric 200
ProCurve(config-route-map)# exit
ProCurve(config)# route-map ISP2 10
ProCurve(config-route-map)# match ip address prefix MultiExit1
ProCurve(config-route-map)# set metric 200
ProCurve(config-route-map)# route-map ISP2 20
ProCurve(config-route-map)# match ip address prefix MultiExit2
ProCurve(config-route-map)# set metric 160
ProCurve(config-route-map)# exit
ProCurve(config)# router bgp 1
ProCurve(config-bgp)# neighbor 1.1.1.1
ProCurve(config-bgp-neighbor)# route-map ISP1 out
ProCurve(config-bgp-neighbor)# neighbor 2.2.2.2
ProCurve(config-bgp-neighbor)# route-map ISP2 out
