Configuring IPv6 IS-IS between PE and CE

An IPv6 IS-IS process belongs to the public network or a single VPN instance. If you create an IPv6 IS-IS

process without binding it to a VPN instance, the process belongs to the public network.
To configure IPv6 IS-IS between PE and CE:

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 PEs.
On CEs, create a normal IPv6 IS-IS

process.

3.

Configure a network entity
title for the IS-IS process.

network-entity net

Not configured by default

4.

Enable the IPv6 capacity for

the IS-IS process.

ipv6 enable

Disabled by default

5.

Return to system view.

quit

N/A

6.

Enter interface view.

interface interface-type
interface-number

N/A

7.

Enable the IPv6 capacity for
the IS-IS process on the

interface.

isis ipv6 enable [ process-id ]

Disabled by default

NOTE:

For more information about IPv6 IS-IS, see

Layer 3—IP Routing Configuration Guide.

Configuring EBGP between PE and CE

1.

Configurations on a PE

To configure EBGP between PE and CE:

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Enable BGP and enter BGP
view.

bgp as-number N/A

3.

Enter IPv6 BGP-VPN instance
view.

ipv6-family vpn-instance
vpn-instance-name

Required

4.

Configure the CE as the VPN
EBGP peer.

peer ipv6-address as-number
as-number

Required

5.

Redistribute the routes of the
local CEs.

import-route protocol [ process-id ]
[ med med-value | route-policy

route-policy-name ] *

A PE needs to redistribute the

routes of the local CEs into its VPN
routing table so that it can

advertise them to the peer PE.

6.

Configure a filtering policy to
filter the routes to be

advertised.

filter-policy { acl6-number |
ipv6-prefix ipv6-prefix-name }

export [ direct | isisv6 process-id |
ripng process-id | static ]

Optional
By default, BGP does not filter

routes to be advertised.
