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,
ensuring 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. 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.
ipv6 import-route protocol
[ process-id ] [ allow-ibgp ] [ cost
cost | [ level-1 | level-1-2 |
level-2 ] | route-policy
route-policy-name | tag tag ] *
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. quit N/A
7. Enter interface view.
interface interface-type
interface-number
N/A
8. Enable the IPv6 IS-IS process
on the interface.
isis ipv6 enable [ process-id ]
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.
1. Configure the MCE:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter BGP view. bgp as-number 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 } as-number
as-number
By default, no BGP peer is
configured.
