Abstract
An automated method for ascertaining interconnectivity in a network comprises operating a customer edge device at a site that is physically linked with at least one provider edge router and communicates directly with peer sites via a virtual private network (VPN) connection. Inter-site connectivity is discovered among a plurality of customer edge devices in the network and effective communication paths among the plurality of customer edge devices across geographically distributed sites are presented.
Claims20
A network apparatus comprising:
- a customer edge device comprising:
- an interface configured for connecting to a network;
- and
- a logic coupled to the interface that operates the customer edge device at a site physically linked with at least one provider edge router and communicates directly with peer sites via a virtual private network (VPN) connection, discovers inter-site connectivity of established routing paths among a plurality of customer edge devices in the network wherein the routing paths are established using a predetermined routing protocol, and creates corresponding VPN communication path connections among the plurality of customer edge devices across geographically distributed sites.
An automated method for ascertaining interconnectivity in a network comprising:
- operating a customer edge device at a site that is physically linked with at least one provider edge router and communicates directly with peer sites via a virtual private network (VPN) connection;
- establishing routing paths using a predetermined routing protocol;
- discovering inter-site connectivity of established routing paths among a plurality of customer edge devices in the network;
- and
- creating corresponding VPN communication path connections among the plurality of customer edge devices across geographically distributed sites.
An article of manufacture comprising:
- a controller usable medium having a computable readable program code embodied therein for automatically ascertaining interconnectivity in a network, the computable readable program code further comprising:
- a code adapted to cause the controller to operate a customer edge device at a site that is physically linked with at least one provider edge router and communicates directly with peer sites via a virtual private network (VPN) connection;
- a code adapted to cause the controller to establish routing paths using a predetermined routing protocol:
- a code adapted to cause the controller to discover inter-site connectivity of established routing paths among a plurality of customer edge devices in the network;
- and
- a code adapted to cause the controller to create corresponding VPN communication path connections among the plurality of customer edge devices across geographically distributed sites.
