Detailed Description

There should be one node per PIM instance. There should be one instance per address family.

Constructor for a given address family, module ID, and event loop.

Parameters:

family	the address family (AF_INET or AF_INET6 for IPv4 and IPv6 respectively).
module_id	the module ID (xorp_module_id). Should be XORP_MODULE_PIMSM Note: if/after PIM-DM is implemented, XORP_MODULE_PIMDM would be allowed as well.
eventloop	the event loop to use.

[virtual]

Destructor

Set the current protocol version.

The protocol version must be in the interval [PIM_VERSION_MIN, PIM_VERSION_MAX].

Parameters:

proto_version

Returns: XORP_OK on success, otherwise XORP_ERROR.

Start the node operation.

Returns: XORP_OK on success, otherwise XORP_ERROR.

Reimplemented from ProtoNode.

Stop the node operation.

Gracefully stop the PIM protocol. The graceful stop will attempt to send Join/Prune, Assert, etc. messages for all multicast routing entries to gracefully clean-up state with neighbors. After the multicast routing entries cleanup is completed, PimNode::final_stop() is called to complete the job. If this method is called one-after-another, the second one will force calling immediately PimNode::final_stop() to quickly finish the job. This function, unlike start(), will stop the protocol operation on all interfaces.

Returns: XORP_OK on success, otherwise XORP_ERROR.

Reimplemented from ProtoNode.

Completely stop the node operation.

This method should be called after PimNode::stop() to complete the job.

Returns: XORP_OK on success, otherwise XORP_ERROR.
