Usage guidelines
IS-IS interfaces by default advertise their IPv6 prefixes in LSPs. Use this command to disable an interface
from advertising its IPv6 prefix in LSPs. This enhances network security by preventing IP routing to the
interval nodes and speeds up network convergence.
Examples
# Enable prefix suppression on GigabitEthernet 2/1/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] isis ipv6 prefix-suppression
isis ipv6 tag
Use isis ipv6 tag to configure the tag value on an interface.
Use undo isis ipv6 tag to restore the default.
Syntax
isis ipv6 tag tag
undo isis ipv6 tag
Default
No tag value is configured on an interface.
Views

Parameters
tag: Specifies a tag value in the range of 1 to 4294967295.
Usage guidelines
This command takes effect when the link cost style is wide, wide-compatible, or compatible.
When IS-IS advertises a prefix with a tag value, IS-IS adds the tag to the IP reachability information TLV
of the prefix.
Examples
# Configure the tag value as 4294967295 on GigabitEthernet 2/1/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] isis ipv6 tag 4294967295
ispf enable
Use ispf enable to enable IPv6 IS-IS incremental SPF (ISPF).
Use undo ispf enable to disable IPv6 IS-IS ISPF.
