Configuring Join/Prune Message Sizes - HP A8800 Configuration Manual

Step
6. Configure the join/prune
timeout time.
7. Configure assert timeout time.
NOTE:
If there are no special networking requirements, we recommend that you use the default settings.

Configuring join/prune message sizes

A larger join/prune message size will result in loss of a larger amount of information when a message
is lost; with a reduced join/message size, the loss of a single message will bring relatively minor impact.
By controlling the maximum number of (S, G) entries in a join/prune message, you can effectively reduce
the number of (S, G) entries sent per unit of time.
To configure join/prune message sizes:
Step
1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Configure the maximum size
of a join/prune message.
4. Configure the maximum
number of (S, G) entries in a
join/prune message.
Configuring PIM to work with BFD
PIM uses hello messages to elect a DR for a multi-access network. The elected DR will be the only multicast
forwarder on the multi-access 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. To start a new DR election process immediately after the original DR fails, enable PIM to
work with Bidirectional Forwarding Detection (BFD) on a multi-access 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
multi-access network, so that the PIM neighbors can fast detect DR failures and start a new DR election
process.
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.
