ABSTRACT:
Techniques and apparatus that allow for accurate determination of network topology utilizing multicast groups are provided. A multicast group may be established that contains a set of VPN endpoints to be monitored. By sending ping packets from each provider edge endpoint to the multicast group, ping responses (with unicast addresses for responders) may be collected and analyzed to determine reachability of the endpoints.
