System and method to determine connectivity of a VPN secure tunnel
TLDR
In this article, a method and system for determining the connectivity of a virtual private network IP security (IPSec) tunnel between two network elements by originating a plurality of connection tests between the network elements is presented.Abstract:
A method and system for determining the connectivity of a virtual private network IP security (IPSec) tunnel between two network elements by originating a plurality of connection tests between the network elements. The first network element transmits a connectivity test message to the second network element over the secure tunnel upon receipt of an initiate connectivity test command. The secure tunnel includes two unidirectional tunnels. The second network element receives the connectivity test message over the first unidirectional secure tunnel and transmits a response back to the first network element over the second unidirectional secure tunnel. The number of successful responses received from the second network element are accumulated and the results are reported back to the source of the connectivity test command.read more
