4.
Enable the PE to exchange
labeled routes with the
ASBR PE in the same AS.
peer
{
group-name
|
ip-address
}
label-route-capability
By default, the PE does not
advertise labeled routes to the
IPv4 peer/peer group.
5.
Configure the PE of another
AS as the EBGP peer.
peer
{
group-name

ip-address
}
as-number
as-number
N/A
6.
Enter BGP-VPNv6
subaddress family view.
ipv6-family vpnv6
N/A
7.
Enable the PE to exchange
BGP VPNv6 routing
information with the EBGP
peer.
peer
ip-address
enable
N/A
8.
Configure the PE not to
change the next hop of a
route when advertising it to
the peer.
peer
ip-address
next-hop-invariable
Optional.
Required only when RRs are
used to advertise VPNv6 routes,
where the next hop of a route
advertised between RRs cannot
be changed.
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. For more information, see "Configuring
MPLS L3VPN."
Configuring the routing policy
After you configure and apply a routing policy on an ASBR PE, it does the following:
•
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. For more
information, see "
"
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.
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.
