Configuring routing between an MCE and a VPN site
Configuring static routing between an MCE and a VPN site
An MCE can reach a VPN site through a static route. Static routing on a traditional CE is globally
effective and thus does not support address overlapping among VPNs. An MCE supports binding a static
route with a VPN instance, so that the static routes of different VPN instances can be isolated from each
other.
To configure a static route to a VPN site:
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
|
mask-length
} {
next-hop-address
[
public
]
[
track
track-entry-number
] |
interface-type
interface-number
[
next-hop-address
] |
vpn-instance
d-vpn-instance-name

[
track
track-entry-number
] } [
permanent
] [
preference
preference-value
] [
tag

] [
description

]
By default, no static
route is configured.
Perform this
configuration on the
MCE. On the VPN
site, configure a
normal static route.
3.
(Optional.) Configure
the default preference
for static routes.
ip route-static default-preference
default-preference-value
The default setting is
60.
Configuring RIP between an MCE and a VPN site
A RIP process belongs to the public network or a single VPN instance. If you create a RIP process without
binding it to a VPN instance, the process belongs to the public network. Binding RIP processes to VPN
instances can isolate routes of different VPNs.
To configure RIP between an MCE and a VPN site:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Create a RIP process for a
VPN instance and enter RIP
view.
rip
[
process-id
]
vpn-instance
vpn-instance-name
Perform this configuration on the
MCE. On the VPN site, create a
normal RIP process.
3.
Enable RIP on the interface
attached to the specified
network.
network
network-address
By default, RIP is disabled on an
interface.
4.
Redistribute remote site routes
advertised by the PE.

By default, no route is redistributed
into RIP.
5.
(Optional.) Configure the
default cost value for the
redistributed routes.

value
If you do not specify a default cost
value, the default cost value is 0.
