Usage guidelines
By default, an OSPFv3 interface advertises all of its prefixes in LSAs. To speed up OSPFv3
convergence, you can suppress interfaces from advertising all of their prefixes. This feature helps
improve network security by preventing IP routing to the suppressed networks.
To disable an OSPFv3 process from advertising the prefixes of loopback and passive interfaces,
configure prefix suppression on the interfaces by using the
ospfv3 prefix-suppression
command.
When prefix suppression is enabled:
•
OSPFv3 does not advertise the prefixes of suppressed interfaces in Type-8 LSAs.
•
On broadcast and NBMA networks, the DR does not advertise the prefixes of suppressed
interfaces in Type-9 LSAs that reference Type-2 LSAs.
•
On P2P and P2MP networks, OSPFv3 does not advertise the prefixes of suppressed interfaces
in Type-9 LSAs that reference Type-1 LSAs.
Examples
# Enable prefix suppression for OSPFv3 process 100.
<Sysname> system-view
[Sysname] ospfv3 100
[Sysname-ospfv3-100] prefix-suppression
