Setting The Maximum Size Of A Join Or Prune Message; Enabling Bfd For Ipv6 Pim; Enabling Ipv6 Pim Passive Mode - HP FlexFabric 5950 series Configuration Manual

3. Set the hello interval.
4. Set the triggered hello delay.
5. Set the join/prune interval.
6. Set the joined/pruned state
holdtime.

Setting the maximum size of a join or prune message

The loss of an oversized join or prune message might result in loss of massive information. You can
set a small value for the size of a join or prune message to reduce the impact.
To set the maximum size of a join or prune message:
Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Set the maximum size of a
join or prune message.

Enabling BFD for IPv6 PIM

If a DR on a shared-media network fails, a new DR election process will start after the DR ages out.
However, it might take a long period of time before other routers detect the link failures and trigger a
new DR election. To start a new DR election process immediately after the original DR fails, you can
enable BFD for IPv6 PIM to detect link failures among IPv6 PIM neighbors.
You must enable BFD for IPv6 PIM on all IPv6 PIM routers on a shared-media network. For more
information about BFD, see High Availability Configuration Guide.
You must enable IPv6 PIM-DM or IPv6 PIM-SM on an interface before you configure this feature on
the interface.
To enable BFD for IPv6 PIM:
Step
1. Enter system view.
2. Enter interface view.
3. Enable BFD for IPv6 PIM.

Enabling IPv6 PIM passive mode

To guard against IPv6 PIM hello spoofing, you can enable IPv6 PIM passive mode on a receiver-side
interface. The interface cannot receive or forward IPv6 PIM protocol messages (excluding register,
