5.
Enable BGP to exchange
IPv4 unicast routes with the
peer.

By default, BGP does not
exchange IPv4 unicast routes
with any peer.
6.
Redistribute the IGP routes
of the VPN into BGP.
import-route
protocol
[ {
process-id

all-processes
}
[

] ]
By default, no routes are
redistributed into BGP.
A VPN site must advertise VPN
network addresses to the
connected MCE.
Configuring routing between an MCE and a PE
MCE-PE routing configuration includes the following tasks:
•
Binding the MCE-PE interfaces to VPN instances.
•
Performing route configurations.
•
Redistributing VPN routes into the routing protocol running between the MCE and the PE.
Perform the following configurations on the MCE. Configure the PE in the same way that you
configure a PE in a basic MPLS L3VPN. For more information about configuring the PE, see
"Configuring MPLS L3VPN."
