Chapter 6 Managing PNNI Nodes and PNNI Routing
Managing PNNI Route and Link Selection
Note Release 3 of the MGX switches supports up to 5000 preferred routes per switch.
A preferred route consists of a sequential list of nodes and links between nodes that stretch from the local
node to the destination node. Each node and link in the preferred route must be within the same peer
group as the originating node. A node can appear only once in the preferred route. Each preferred route
supports a Maximum of 19 hops away from the local node (up to 20 nodes, including the local node, or
19-NNI links).
Configuring a Preferred Route
Use the following procedure to configure a preferred route.
Step 1 Enter the dsptopondlist command to see the nodes in this database. These are the nodes you can use to
set up your preferred route.
