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

N/A
2.
Create an IPv6 IS-IS process
for a VPN instance and enter
IS-IS view.

[
process-id
]

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.
Enable IPv6 for the IPv6
IS-IS process.
ipv6 enable
By default, IPv6 is disabled.
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.

By default, no IPv6 IS-IS process
is enabled.
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. You can also configure the filtering of received and advertised routes.
