DSwT connecting areas with manual TAP tunnels
...................................................................................................................................................................................................................................
Introduction
The TAP mechanism does not work across IS-IS Areas because it distributes
information using IS-IS Level 1 LSPs. However, it is likely to have a considerable
number of nodes in the OSI network and multiple areas.
Connecting areas
To allow DSwT nodes to communicate across IS-IS Areas enjoying the benefits of the
auto-provisioning, a pair of “tunnels” must be manually configured between the areas.
This principle is illustrated in the following figure.
Connecting areas principle
A pair of provisioned “Tunnels” connecting any two nodes, one from each area,
provides bi-directional communication between the Areas.
NOTE: TAP “Tunnels” are not transitive. That is a “Tunnel” connecting Areas A and
B, and a “Tunnel” connecting Areas B and C does NOT connect Areas A and C. A
separate “Tunnel” between Areas A and C is needed.
