Enterprise virtual private LAN services
View Patent ↗Example embodiments are directed to methods of configuring a virtual private local area network service for an enterprise. At least one method includes assigning a virtual private local area network instance to a first node within a network. A first node attempts to establish a label distribution protocol session between the first node and at least one other node within the network based on an interior gateway protocol map. The interior gateway protocol map identifies the at least one other node and nodes connected to the at least one other node. The virtual private local area network service is established based on the label distribution protocol sessions that are established.
1. A method of configuring a virtual private local area network service, the method comprising:
assigning, by an operator, a virtual private local area network instance to a first node;
transmitting, by the first node, a signal to establish a label distribution protocol session between the first node and at least one other node within the network based on an interior gateway protocol map, the interior gateway protocol map identifying the at least one other node and nodes connected to the at least one other node; and
establishing, by the first node, the virtual private local area network service based on the label distribution protocol sessions that are established.
2. The method of claim 1 , further comprising:
creating a service distribution point identification when a label distribution protocol session is established.
3. The method of claim 2 , further comprising:
exchanging service labels between the first node and the at least one other node.
4. The method of claim 1 , wherein the transmitting is performed periodically.
5. The method of claim 1 , wherein the transmitting is performed when another node is added to the interior gateway protocol map.
6. The method of claim 1 , wherein the assigning includes assigning a virtual circuit identification as the virtual private local area network instance.
7. The method of claim 6 , wherein the transmitting includes establishing a label distribution protocol session when the first node and the at least one other node have matching virtual circuit identifications.
8. The method of claim 7 , further comprising:
exchanging service labels between the first node and the at least one other node.
9. The method of claim 1 , wherein the transmitting includes logging and reporting unsuccessful attempts to a user of the first node.
10. The method of claim 1 , wherein the interior gateway protocol map identifies a loopback address of the at least one other node.
11. A method of configuring a virtual private local area network service, the method comprising:
assigning, by an operator, a virtual private local area network instance to a first node;
transmitting, by the first node, a signal to establish a label distribution protocol session between the first node and at least one other node within the network based on an interior gateway protocol map, the interior gateway protocol map identifying the at least one other node and nodes connected to the at least one other node; and
establishing, by the first node, the virtual private local area network service based on the label distribution protocol sessions that are established, wherein
the interior gateway protocol map identifies a loopback address of the at least one other node, and
the transmitting includes establishing label switched paths within the virtual private local area network service using a label distribution protocol and the loopback address of the at least one other node.
12. A method of discovering nodes in a virtual private local area network service using an interior gateway protocol, the method comprising:
receiving, by one of a plurality of nodes, a list of the plurality of nodes from an interior gateway protocol map, the interior gateway protocol map being established by the interior gateway protocol and identifying connections between the plurality of nodes; and
transmitting, by the one of the plurality of nodes, a signal to establish a label distribution protocol session with at least one other of the plurality of nodes.
13. The method of claim 12 , wherein the transmitting includes establishing a label distribution protocol session when the first node and the at least one other node have matching virtual circuit identifications.
14. The method of claim 13 , wherein the transmitting further includes, establishing a label distribution protocol session with the at least one other of the plurality of nodes, wherein a service distribution point identification and a tunnel to the at least one other node is created.
15. The method of claim 14 , wherein the establishing includes exchanging service labels for services between the one of the plurality of nodes and the at least one other plurality of nodes.
