Step Command

Remarks

7.

(Optional.) Disable setting the
DN bit in OSPFv3 LSAs.

disable-dn-bit-set

By default, when a PE redistributes
BGP routes into OSPFv3 and
creates OSPFv3 LSAs, it sets the

DN bit for the LSAs.
Before using this command, make

sure it does not cause any routing
loops.
Perform this configuration on the
PE.

8.

(Optional.) Ignore the DN bit
in OSPFv3 LSAs.

disable-dn-bit-check

By default, the PE checks the DN bit
in OSPFv3 LSAs.
Before using this command, make
sure it does not cause any routing

loops.
Perform this configuration on the
PE.

9.

(Optional.) Enable the

external route check feature
for OSPFv3 LSAs.

route-tag-check enable

By default, the PE checks the DN bit
in OSPFv3 LSAs to avoid routing

loops.
This command is compatible with

the old protocol (RFC 4577). H3C
recommends not using this

command in the current software

version.
Perform this configuration on the
PE.

10.

Return to system view.

12.

Enable OSPFv3 on the
interface.

ospfv3 process-id area area-id
[ instance instance-id ]

By default, OSPFv3 is disabled on
an interface.
Perform this configuration on the

PE.

Configuring IPv6 IS-IS between a PE and a 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.
For more information about IPv6 IS-IS, see Layer 3—IP Routing Configuration Guide.
To configure IPv6 IS-IS between a PE and a CE:

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.

isis [ process-id ] vpn-instance
vpn-instance-name

Perform this configuration on the
PE. On the CE, create a common
IPv6 IS-IS process.
