Combined Linkset Networking

The following figure shows an example of combined linkset networking:

Node A has a route to Node F through a combined linkset where both lsAB and lsAC have the same relative cost for their respective routes, making up a cost group.

Thus, the following conditions holds true:

• The traffic sent from Node A over Linksets lsAB and lsAC will be distributed equally between both linksets.
• The status of the routeset of Node A for which the destination is Node F, follows the rules shown in the following table:
