Abstract:
In one embodiment, a method includes determining a secure path through a first plurality of network nodes within a network and determining an alternate secure path through a second plurality of network nodes within the network. The method also includes routing network traffic through the first plurality of network nodes of the secure path and detecting a failure in the secure path using single-hop BFD authentication. The method further includes rerouting the network traffic through the second plurality of network nodes of the alternate secure path.
