route-target signaling.
host1(config-router-af)#external-paths 2
Configure any additional address family parameters desired for the session.

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.
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.
To configure a VRF to provide BGP VPN services:
Create the VRF.
1.
host1(config)#virtual-router vr1
host1:vr1(config)#ip vrf vrfA
Assign a route distinguisher to the VRF.
2.
host1:vr1(config-vrf)#rd 100:100
Set the route-target import and route-target export lists for the VRF.
3.
host1:vr1(config-vrf)#route-target import 100:1
host1:vr1(config-vrf)#route-target export 100:1
(Optional) Set import and export maps for the VRF.
