Detailed Description

Update Route Entry in database for specified route.

If the route does not exist or the values provided differ from the existing route, then an update is placed in the update queue.

Parameters:

net	the network route being updated.
nexthop	the corresponding nexthop address.
cost	the corresponding metric value as received from the peer.
tag	the corresponding route tag.
peer	the peer proposing update.

Returns: true if an update occurs, false otherwise.

Flatten routing table representation from Trie to Vector.

Parameters:

routes

vector where routes are to be appended.

Resolve a route and take a reference to it. While the reference exists the route will not be deleted from memory, though may be remove from table.

Parameters:

net	network to be resolved.
cdbe	reference pointer to route entry.

Returns: true if route resolves, false otherwise.
