■ Use to set the maximum number of received external BGP best paths allowed
for route-target signaling.
■ Specify a value in the range 1–255; the default value is 1.
■ This command takes effect immediately; it does not bounce the session.
■ This command applies to only the route-target address family.
■ Example 1
host1(config-router)#external-paths 45
■ Example 2
host1:vr1(config-router-af)#external-paths 45
■ Use the no version to restore the default value, 1.

Multicast Routing Configuration Guide.
Configuring BGP VPN Services
To configure a router to provide BGP VPN services, you must perform some tasks
once per PE router and some tasks for each VRF on the PE router.
VRF Configuration Tasks
To configure a VRF to provide BGP VPN services:
1. Create the VRF.
host1(config)#virtual-router vr1
host1:vr1(config)#ip vrf vrfA
2. Assign a route distinguisher to the VRF.
host1:vr1(config-vrf)#rd 100:100
3. Set the route-target import and route-target export lists for the VRF.
host1:vr1(config-vrf)#route-target import 100:1
host1:vr1(config-vrf)#route-target export 100:1
4. (Optional) Set import and export maps for the VRF.
host1:vr1(config-vrf)#import map Another-route-map
host1:vr1(config-vrf)#export map A-route-map
host1:vr1(config-vrf)#exit
