Abstract

A method for IP Security within Multi-Topology Routing is disclosed. Disclosed methods may also include IKE extensions. A route eligible for IPSec protection is injected into a topology routing table. Network traffic can then be protected in accordance with a security session, such as an IPSec session, between a first network node and a second network node and forwarded through a selected topology to take advantage of the service-differentiation capabilities of MTR.
