Multi

A simple multi-area IS-IS configuration with two OSPF domains to support VoIP access to the network. The VoIP transits the IS-IS backbone. The phones are configured for Private Line Automatic Ringdown (PLAR), which provides a convenient IS-IS configuration ping. If IS-IS is working correctly, lifting either handset results in a ring at the other side.
