Setting The Maximum Size Of Each Join Or Prune Message; Enabling Pim To Work With Bfd; Displaying And Maintaining Pim - HP 5920 series Configuration Manual

Setting the maximum size of each 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 each join or prune message to reduce the impact.
To set the maximum size of each join or prune message:
Step
1. Enter system view.
2. Enter PIM view.
3. Set the maximum size of each
join or prune message.

Enabling PIM to work with BFD

PIM uses hello messages to elect a DR for a shared-media network. The elected DR is the only multicast
forwarder on the shared-media network.
If the DR fails, a new DR election process will start after the DR is aged out. However, it might take a long
period of time before other routers detect the link failures and trigger a new DR election process. To start
a new DR election process immediately after the original DR fails, enable PIM to work with Bidirectional
Forwarding Detection (BFD) on a shared-media network to detect failures of the links among PIM
neighbors. You must enable PIM to work with BFD on all PIM-capable routers on a shared-media network,
so that the PIM neighbors can fast detect DR failures and start a new DR election process. For more
information about BFD, see High Availability Configuration Guide.
Before you configure this feature on an interface, be sure to enable PIM-DM or PIM-SM on the interface.
To enable PIM to work with BFD:
Step
1. Enter system view.
2. Enter interface view.
3. Enable PIM to work
with BFD.
