| PimVif (PimNode& pim_node, const Vif& vif)
| PimVif |
Constructor for a given PIM node and a generic virtual interface.
Parameters:
| pim_node | the PimNode this interface belongs to. |
| vif | the generic Vif interface that contains various information. |
| ~PimVif ()
| ~PimVif |
[virtual]
| void set_default_config ()
| set_default_config |
Set configuration to default values.
| int set_proto_version (int proto_version)
| set_proto_version |
Set the current protocol version.
The protocol version must be in the interval [PIM_VERSION_MIN, PIM_VERSION_MAX].
Parameters:
| proto_version | the protocol version to set. |
Returns: XORP_OK on success, otherwise XORP_ERROR.
Reimplemented from ProtoUnit.
| int start (string& error_msg)
| start |
Start PIM on a single virtual interface.
Parameters:
| error_msg | the error message (if error). |
Returns: XORP_OK on success, otherwise XORP_ERROR.
| int stop (string& error_msg)
| stop |
Gracefully stop PIM on a single virtual interface.
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, PimVif::final_stop() is called to complete the job.
Parameters:
| error_msg | the error message (if error). |
Returns: XORP_OK on success, otherwise XORP_ERROR.
| int final_stop (string& error_msg)
| final_stop |
Completely stop PIM on a single virtual interface.
This method should be called after PimVif::stop() to complete the job.
Parameters:
| error_msg | the error message (if error). |
Returns: XORP_OK on success, otherwise XORP_ERROR.
| void enable ()
| enable |
Enable PIM on a single virtual interface.
If an unit is not enabled, it cannot be start, or pending-start.
| void disable ()
| disable |
Disable PIM on a single virtual interface.
If an unit is disabled, it cannot be start or pending-start. If the unit was runnning, it will be stop first.
| int pim_recv (const IPvX& src, const IPvX& dst,
int ip_ttl, int ip_tos, bool is_router_alert,
buffer_t *buffer)
| pim_recv |
Receive a protocol message.
Parameters:
| src | the source address of the message. |
| dst | the destination address of the message. |
| ip_ttl | the IP TTL of the message. If it has a negative value it should be ignored. |
| ip_ttl | the IP TOS of the message. If it has a negative value, it should be ignored. |
| is_router_alert | if true, the IP Router Alert option in the IP packet was set (when applicable). |
| buffer | the data buffer with the received message. |
Returns: XORP_OK on success, otherwise XORP_ERROR.
| string flags_string ()
| flags_string |
[const]
Get the string with the flags about the vif status.
TODO: temporary here. Should go to the Vif class after the Vif class starts using the Proto class.
Returns: the C++ style string with the flags about the vif status (e.g., UP/DOWN/DISABLED, etc).
| PimNode& pim_node ()
| pim_node |
[const]
Get the PIM node (PimNode).
Returns: a reference to the PIM node (PimNode).

| int update_primary_and_domain_wide_address (string& error_msg)
| update_primary_and_domain_wide_address |
Update the primary and the domain-wide reachable addresses.
The primary address should be a link-local unicast address, and is used for transmitting the multicast control packets on the LAN. The domain-wide reachable address is the address that should be reachable by all PIM-SM routers in the domain (e.g., the Cand-BSR, or the Cand-RP address).
Parameters:
| error_msg | the error message (if error). |
Returns: XORP_OK on success, otherwise XORP_ERROR.
