Abstract
A method and apparatus for providing dynamic route advertisement based on IP-Sec security associations are disclosed. The method receives a notification for an establishment, a deletion or a modification of a security association for a sub-network. The method then adds or deletes a route for the sub-network based on the security association and dynamically advertises the added or deleted route to one or more peer devices. In one embodiment, the method also receives an advertisement for an added or deleted route from a peer device, identifies at least one IP-Sec client for receiving the advertisement, and establishes or deletes one or more security associations for the at least one identified IP-Sec client.
