2. Configure a VPN site:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter BGP view.
bgp
as-number N/A
3. Configure the MCE as an
IBGP peer.
peer
{ group-name | ip-address
[ mask-length ] }
as-number
as-number
N/A
4. Enter BGP IPv4 unicast
address family view.
address-family ipv4
[
unicast
] N/A
5. Enable BGP to exchange
IPv4 unicast routes with the
peer.
peer
{ group-name | ip-address
[ mask-length ] }
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
}
[
med
med-value ] ]
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."
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
]
[
track
track-entry-number ] |
vpn-instance
d-vpn-instance-name next-hop-address [
track
track-entry-number ] } [
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.
