A method of configuring a network router, wherein the network router comprises a plurality of ingress interfaces, an interface forwarding table assigned to each ingress interface, the method comprising the steps of, for each ingress interface:
- determining if the ingress interface may be used as part of a route from any source node to any destination node in the network;
- and
- removing from the interface forwarding table the forwarding table entries for destination nodes towards which the ingress interface is not used as part of a route from any source node in the network.
A method of configuring a network router, the network router comprising a node forwarding table for the node itself;
- the method comprising the steps of
- determining if the node may be used as part of a route from any source node to any destination node in the network;
- and
- removing from the node forwarding table the forwarding table entries for destination nodes towards which the node is not used as part of a route from any source node in the network.
A network router comprising:
- a plurality of ingress interfaces, and
- an interface forwarding table assigned to each ingress interface;
- wherein at least one of the interface forwarding tables comprises only forwarding table entries for destination nodes towards which the interface is used as part of a route from any source node in the network.
A network router comprising a node forwarding table assigned to the router, wherein the forwarding table comprises forwarding table entries for destination nodes towards which the node is used as part of a route from any source node in the network.
A network router comprising,
- a node forwarding table assigned to the router;
- a plurality of ingress interfaces;
- an interface forwarding table assigned to each ingress interface;
- and
- means for removing from at least one of the interface forwarding tables the forwarding table entries for destination nodes towards which the interface is not used as part of a route from any source node in the network.
A network router comprising
- a node forwarding table assigned to the router itself;
- and
- means for removing the forwarding table entries for destination nodes towards which the node is not used as part of a route from any source node in the network.
