Configuring routing between an MCE and a VPN site
You can configure static routing, RIPng, OSPFv3, IPv6 IS-IS, or EBGP 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 an IPv6 static route. IPv6 static routing on a traditional CE is
globally effective and does not support address overlapping among VPNs. An MCE supports binding
an IPv6 static route with an IPv6 VPN instance, so that the IPv6 static routes of different IPv6 VPN
instances can be isolated from each other.
To configure IPv6 static routing between an MCE and a VPN site:
1. Enter system view.
system-view
N/A
2. Configure an IPv6
static route for an IPv6
VPN instance.
ipv6 route-static
vpn-instance
s-vpn-instance-name ipv6-address prefix-length
{ interface-type interface-number
[ next-hop-address ] | nexthop-address [
public
]
|
vpn-instance
d-vpn-instance-name
nexthop-address } [
permanent
] [
preference
preference-value ] [
tag
tag-value ] [
description
description-text ]
By default, no IPv6 static
route is configured.
Perform this
configuration on the
MCE. On a VPN site,
configure normal IPv6
static routes.
3. (Optional.) Configure
the default preference
for IPv6 static routes.
ipv6 route-static default-preference
default-preference-value
The default preference
for IPv6 static routes is
60.
Configuring RIPng between an MCE and a VPN site
A RIPng process belongs to the public network or a single IPv6 VPN instance. If you create a RIPng
process without binding it to an IPv6 VPN instance, the process belongs to the public network. By
configuring RIPng process-to-IPv6 VPN instance bindings on a MCE, you allow routes of different
VPNs to be exchanged between the MCE and the sites through different RIPng processes, ensuring
the separation and security of IPv6 VPN routes.
For more information about RIPng, see Layer 3—IP Routing Configuration Guide.
To configure RIPng between an MCE and a VPN site:
1. Enter system view.
N/A
2. Create a RIPng process for a
RIPng view.
ripng
[ process-id ]
vpn-instance
vpn-instance-name
Perform this configuration on the
MCE. On a VPN site, configure
normal RIPng.
3. Redistribute
routes advertised by the PE.

allow-ibgp
]

*
By default, no routes are
redistributed into RIPng.
4. (Optional.)
Configure the
default cost value for the
redistributed routes.
default cost
value
The default value is 0.
5. Return to system view.

6. Enter interface view.
