Detailed Description

Base class for the Multicast Routing Information Base Table.

Constructor & Destructor Documentation

MribTable::MribTable ( int family )

Constructor for table of a given address family.

MribTable::MribTable: : The address family (e.g., AF_INET or AF_INET6).

Parameters:

family the address family.

MribTable constructor.

MribTable::~MribTable ( )

Destructor.

MribTable::~MribTable: @:

MribTable destructor. Remove and delete all MRIB entries and cleanup.

Member Function Documentation

void MribTable::abort_pending_transactions ( uint32_t tid )

Abort pending transactions for adding or removing Mrib entries for a given transaction ID.

Parameters:

tid	the transaction ID of the entries to abort.

void MribTable::add_pending_insert	(	uint32_t	tid,
		const Mrib &	mrib
	)

Add a pending transaction to insert a Mrib entry from the table.

The operation is added to the list of pending transactions, but the entry itself is not added to the table (until MribTable::commit_pending_transactions() is called).

Parameters:

tid	the transaction ID.
mrib	the Mrib entry that contains the information about the entry to add.

void MribTable::add_pending_remove	(	uint32_t	tid,
		const Mrib &	mrib
	)

Add a pending transaction to remove a Mrib entry from the table.

the operation is added to the list of pending transaction, but the entry itself is not removed from the table (until MribTable::commit_pending_transactions() is called).

Parameters:

tid	the transaction ID.
mrib	the Mrib entry that contains the information about the entry to remove.

Reimplemented in PimMribTable.

void MribTable::add_pending_remove_all_entries ( uint32_t tid )

Add a pending transaction to remove all Mrib entries from the table.

the operation is added to the list of pending transaction, but the entries themselves is not removed from the table (until MribTable::commit_pending_transactions() is called).

Parameters:

tid	the transaction ID.

Reimplemented in PimMribTable.

iterator MribTable::begin ( ) const [inline]

Get an iterator for the first element.

Returns:: the iterator for the first element.

void MribTable::commit_pending_transactions ( uint32_t tid )

Commit pending transactions for adding or removing Mrib entries for a given transaction ID.

All pending transactions to add/remove Mrib entries for a given transaction ID are processes (see MribTable::add_pending_insert() and MribTable::add_pending_remove() and MribTable::add_pending_remove_all_entries()).

Parameters:

tid	the transaction ID of the entries to commit.

Reimplemented in PimMribTable.

iterator MribTable::end ( ) const [inline]

Get an iterator for the last element.

Returns:: the iterator for the last element.

int MribTable::family ( ) const [inline]

Get the address family.

Returns:: the address family ((e.g., AF_INET or AF_INET6 for IPv4 and IPv6 respectively).

Mrib * MribTable::find ( const IPvX & address ) const

Find the longest prefix match for an address.

Parameters:

address the lookup address.

Returns:: a pointer to the longest prefix Mrib match for address if exists, otherwise NULL.

Reimplemented in PimMribTable.

Mrib * MribTable::find_exact ( const IPvXNet & dest_prefix ) const

Find an exact match for a network address prefix.

Parameters:

dest_prefix the lookup network address prefix.

Returns:: a pointer to the exact Mrib match for dest_prefix if exists, otherwise NULL.

MribLookup * MribTable::find_prefix_mrib_lookup ( const IPvXNet & addr_prefix ) const [private]

Find an exact MribLookip match.

Parameters:

addr_prefix the lookup network address prefix.

Returns:: a pointer to the exact MribLookup match for addr_prefix if exists, otherwise NULL.

Mrib * MribTable::insert ( const Mrib & mrib )

Insert a copy of a Mrib entry.

Note: if there is an existing Mrib entry for the same prefix, the old entry is deleted.

Parameters:

mrib	the entry to insert.

Returns:: a pointer to the inserted entry on success, otherwise NULL.

bool MribTable::is_preserving_removed_mrib_entries ( ) const [inline]

Test if the removed Mrib entries are preserved or deleted.

Returns:: true if the removed Mrib entries are preserved, otherwise false.

void MribTable::remove ( const IPvXNet & dest_prefix )

Remove from the table a Mrib entry for a given destination prefix.

Parameters:

dest_prefix the destination prefix of the entry to remove.

void MribTable::remove ( const Mrib & mrib )

Remove a Mrib entry from the table.

Parameters:

mrib	a Mrib with information about the entry to remove.

void MribTable::remove_mrib_entry ( Mrib * mrib ) [private]

Remove a Mrib entry from the table.

The Mrib entry itself is either deleted or added to the list with removed entries.

Parameters:

mrib	the Mrib entry to remove.

void MribTable::remove_mrib_lookup ( MribLookup * mrib_lookup ) [private]

Remove a subtree of entries in the table.

Remove recursively all MribLookup below and including the given mrib_lookup entry.

Parameters:

mrib_lookup the MribLookup entry that is the root of the subtree to remove.

list<Mrib *>& MribTable::removed_mrib_entries ( ) [inline]

Get a reference to the list with removed Mrib entries.

Returns:: a reference to the list with removed Mrib entries.

void MribTable::set_is_preserving_removed_mrib_entries ( bool v ) [inline]

Enable or disable the preserving of the removed Mrib entries.

Parameters:

v	if true, then the removed Mrib entries are preserved otherwise they are deleted.

size_t MribTable::size ( ) const [inline]

Get the number of Mrib entries in the table.

Returns:: the number of Mrib entries in the table.

void MribTable::update_entry_vif_index	(	const IPvXNet &	dest_prefix,
		uint32_t	vif_index
	)

Update the vif index of a Mrib entry.

Parameters:

dest_prefix	the destination prefix of the Mrib entry to update.
vif_index	the new vif index of the Mrib entry.
