Configuring the ASBR PEs
In the inter-AS IPv6 VPN option C solution, an inter-AS LSP is required, and the routes advertised between
the relevant PEs and ASBRs must carry MPLS label information. The configuration is the same as that in
the Inter-AS IPv4 VPN option C solution (see the chapter “Configuring MPLS L3VPN”).
Configuring the routing policy
After you configure and apply a routing policy on an ASBR PE, it:
• Assigns MPLS labels to routes received from the PEs in the same AS before advertising them to the
peer ASBR PE.
• Assigns new MPLS labels to the labeled routes to be advertised to the PEs in the same AS.
The configuration is the same as that in the Inter-AS IPv4 VPN option C solution (see the chapter
“Configuring MPLS L3VPN”).
Configuring routing on an MCE
An MCE implements service isolation through route isolation. MCE routing configuration includes:
• MCE-VPN site routing configuration
• MCE-PE routing configuration
On the PE in an MCE network environment, disable routing loop detection to avoid route loss during
route calculation and disable route redistribution between routing protocols to save system resources.
Configuration prerequisites
Before you configure routing on an MCE, complete the following tasks:
• On the MCE, configure VPN instances, and bind the VPN instances with the interfaces connected
to the VPN sites and those connected to the PE.
• Configure the link layer and network layer protocols on related interfaces to ensure IP connectivity.
Configuring routing between MCE and VPN site
Configuring static routing between MCE and 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 an IPv6 VPN instance, so that the static routes of different IPv6 VPN instances can be isolated
from each other.
To configure static routing between MCE and VPN site:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure IPv6 static routes
for an IPv6 VPN
instanceN/A.
ipv6 route-static ipv6-address prefix-length
{ interface-type interface-number
[ next-hop-address ] | next-hop-address |
vpn-instance d-vpn-instance-name
nexthop-address } [ preference
preference-value ]
Required
Use either command.
Perform this
configuration on the
MCE. On a VPN site,
