Step Command Remarks
5. Enable BGP to exchange
IPv4 unicast routes with the
peer.
peer { group-name | ip-address }
enable
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 }
[ allow-direct | med med-value |
route-policy route-policy-name ]
* ]
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. For information about configuring the PE, see the
documentation for the PE.
Configuring static routing between an MCE and a PE
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure a static route
for a VPN instance.
ip route-static vpn-instance s-vpn-instance-name
dest-address { mask-length | mask } { interface-type
interface-number [ next-hop-address ] |
next-hop-address [ public ] | vpn-instance
d-vpn-instance-name next-hop-address }
[ permanent ] [ preference preference-value ] [ tag
tag-value ] [ description description-text ]
By default, no static
route is configured.
3. (Optional.) Configure
the default preference for
static routes.
ip route-static default-preference
default-preference-value The default preference is
60.
Configuring OSPF between an MCE and a PE
Step Command Remarks
1. Enter system view. system-view N/A
2. Create an OSPF process for a
VPN instance and enter OSPF
view.
