Abstract
Systems and methods for using routing protocol extensions to improve spoke to spoke communication in a computer network are disclosed. Embodiments provide systems and methods to establish a tunnel between a first spoke and a hub, exchange routing information between the first spoke and the hub using a routing protocol, extend the routing protocol and an associated database to include next hop mapping information, and establish a tunnel between the first spoke and a second spoke according to information in the database.
Claims15
A method comprising:
- establishing a tunnel between a first node and a second node;
- exchanging routing information between the first node and the second node using a routing protocol;
- extending the routing protocol and an associated database to include next hop mapping information;
- and
- establishing a tunnel between the first node and a third node according to information in the database.
An apparatus comprising:
- a first node to establish a tunnel between the first node and a second node, the first node exchanging routing information with the second node using a routing protocol;
- means for extending the routing protocol and an associated database to include next hop mapping information;
- and
- the first node to establish a tunnel between the first node and a third node according to information in the database.
A hub apparatus comprising:
- a first spoke interface to receive a routing protocol message from a spoke, the routing protocol message including next hop mapping information for a first spoke;
- a hub database to store the next hop mapping information for the first spoke;
- and
- a second spoke interface to advertise the next hop mapping information for the first spoke to a second spoke via a routing protocol.
