Chapter 10 Managing PNNI Routing
Cajun M770 ATM Switch User’s Guide 111
In addition, the table distinguishes between nodes that are reachable, and those
that are not reachable. Reasons for a node to be non-reachable node are:
• One or more PTSEs generated by this node were received at the local node, but
the Nodal Info PTSE of that node was not one of them.
• The Nodal Info PTSE of that node was received, however, there is no valid
route to that node. A route may be non-valid if one or more links on that route
are non-routable.
• A node may be non-reachable if one of the nodes on the path is a non-transit
node.
Reachable addresses are grouped to Internal and Exterior Reachable Addresses
(RAs). Internal RAs are ATM addresses that are part of the PNNI domain. The
switches learned them using ILMI and advertised them in Internal RA IGs. Exterior
RAs are ATM addresses that are not part of the PNNI domain. They were learned by
the switch using a private protocol or manually configured, and advertised using
Exterior RA IGs. Finally, the total number of different PTSEs received at this node is
displayed.
Global topology links
Use the following command to display the global topology links:
This represents the fact that 2 Horizontal Links PTSEs for 2 routable uni-directional
links exist in the local node topology database. The link is identified by the node ID
and the port number of its ends.
If the link does not exist, an ‘X’ will be displayed on the vertical line.
