Usage guidelines
If you want to use prefix suppression, HP recommends that you configure prefix suppression on all OSPF
routers.
When prefix suppression is enabled:
• On P2P and P2MP networks, OSPF does not advertise Type-3 links in Router LSAs.
• On broadcast and NBMA networks, the DR generates Network LSAs with a mask length of 32 to
suppress network routes. If no neighbors exist, the DR also does not advertise the primary IP
addresses of interfaces in Router LSAs.
• OSPF does not advertise the host routes of loopback interfaces.
Examples
# Enable prefix suppression for OSPF process 1.
<Sysname> system-view
[Sysname] ospf 1
[Sysname-ospf-1] prefix-suppression
