C onfiguring IPv6 IS-IS between an MCE and a VPN site
5 8 0 B
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
1. Enter system view.
2. Create an IPv6 IS-IS process
for a VPN instance and enter
IS-IS view.
3. Configure a network entity
title for the IS-IS process.
4. Create the IS-IS IPv6 unicast
address family and enter its
view.
5. (Optional.) Redistribute
remote site routes advertised
by the PE.
6. Return to system view.
7. Enter interface view.
8. Enable the IPv6 IS-IS
process on the interface.
C onfiguring EBGP between an MCE and a VPN site
5 8 1 B
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
1. Enter system view.
2. Enter BGP instance view.
3. Enter BGP-VPN instance
view.
4. Specify an IPv6 BGP peer
in an AS.
5. Enter BGP-VPN IPv6

Remarks
N/A
Perform this configuration on the
MCE. On a VPN site, configure
common IPv6 IS-IS.
By default, no NET is configured.
By default, the IS-IS IPv6 unicast
address family is not created.
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
