processes. This ensures the separation and security of IPv6 VPN routes. For more information about
IPv6 IS-IS, see
Layer 3—IP Routing Configuration Guide
.
To configure IPv6 IS-IS between an MCE and a VPN site:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Create an IPv6 IS-IS process
for a VPN instance and enter
IS-IS view.
isis
[
process-id
]
vpn-instance
vpn-instance-name
Perform this configuration on the
MCE. On a VPN site, configure
common IPv6 IS-IS.
3.
Configure a network entity
title for the IS-IS process.
network-entity net
By default, no NET is configured.
4.
Create the IS-IS IPv6 unicast
address family and enter its
view.
address-family ipv6
[
unicast
]
By default, the IS-IS IPv6 unicast
address family is not created.
5.
(Optional.) Redistribute
remote site routes advertised
by the PE.

By default, no routes are
redistributed to IPv6 IS-IS.
If you do not specify the route
level in the command,
redistributed routes are added to
the level-2 routing table.
6.
Return to system view.

7.
Enter interface view.
interface interface-type

8.
Enable the IPv6 IS-IS
process on the interface.
isis ipv6 enable
[
process-id
]
By default, no IPv6 IS-IS process
is enabled on the interface.
Configuring EBGP between an MCE and a VPN site
To use EBGP between an MCE and IPv6 VPN sites, you must configure a BGP peer for each IPv6
VPN instance on the MCE, and redistribute the IGP routes of each VPN instance on the IPv6 VPN
sites.
1.
Configure the MCE:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter BGP instance view.
bgp
as-number
[
instance
instance-name
]
[
multi-session-thread
]
N/A
3.
Enter BGP-VPN instance
view.
ip vpn-instance
vpn-instance-name
N/A
4.
Specify an IPv6 BGP peer
in an AS.
peer
{
group-name
|
ipv6-address
[
prefix-length
] }
as-number
as-number
By default, no BGP peers exist.
5.
Enter BGP-VPN IPv6
unicast address family
view.
address-family ipv6
[
unicast
]
N/A
6.
Enable BGP to exchange
IPv6 unicast routes with the
specified peer.
peer
{
group-name
|
ipv6-address
[
prefix-length
] }
enable
By default, BGP does not
exchange IPv6 unicast routes
with any peer.
7.
Redistribute remote site
routes advertised by the
PE.
import-route

[ {
process-id

By default, no route
redistribution is configured.
