Configuring OSPFv3 between IPv6 MCE and VPN site 
An OSPFv3 process belongs to the public network or a single IPv6 VPN instance. If you create an 
OSPFv3 process without binding it to an IPv6 VPN in stance, the process belongs to the public network. 
By configuring OSPFv3 process-to-IPv6 VPN instance bindings on an IPv6 MCE, you allow routes of 
different IPv6 VPNs to be exchanged between the  IPv6 MCE and the sites through different OSPFv3 
processes, ensuring the separation and security of IPv6...

Step Command Remarks 
4.  Enable the IPv6 capacity for 
the IPv6 IS-IS process.  ipv6 enable 
Disabled by default. 
5.  Redistribute remote site routes 
advertised by the PE.  ipv6 import-route 
protocol 
[ process-id  ] [ allow-ibgp  ] [ cost 
cost | [  level-1 | level-1-2  | 
level-2  ] | route-policy 
route-policy-name  | tag  tag ] *  Optional. 
By default, no routes from any 
other routing protocol are 
redistributed to IPv6 IS-IS. 
If you do not specify the route level 
in the command,...

 424 
 NOTE: 
After you configure an IPv6 BGP VPN instance, the IPv6 BGP  route exchange for the IPv6 VPN instance is
the same with the normal IPv6 BGP VPN route exchange.  
 
2.  Configure a VPN site:

Configuring RIPng between IPv6 MCE and PE 
 
Step Command Remarks 
1.  Enter system view.

2.  Create a RIPng process for an 
IPv6 VPN instance and enter

routing protocol is redistributed 
into RIPng.

 NOTE: 
IPv6 BGP runs within a VPN in the same wa y as it runs within a public network.  
 
Resetting BGP connections 
When BGP configuration changes, you can use the soft reset function or reset BGP connections to make 
new configurations take effect. Soft reset requires that BGP peers have route refreshment capability 
(supporting Route-Refresh messages). 
Use the following commands to hard reset or soft reset BGP connections: 
 
Step Command Remarks 
1.  Soft reset the IPv6 BGP 
connections in a...

Configuration procedure 
Assume that the system name of the IPv6 MCE device is MCE, the system names of the edge devices of 
VPN 1 and VPN 2 are VR1 and VR2, respectively, and the system name of PE 1 is PE1. 
1. Configure the VPN instances on the MCE and PE 1. 
# On the MCE, configure VPN instances  vpn1 and  vpn2, and specify a RD and route targets for 
each VPN instance.
