Cisco IOS Software-Based PNNI Node


For completeness, we include in the picture a Cisco IOS Software-based PNNI node. The PNNI configuration is shown in Example 10-30, following our address scheme.

Example 10-30. PNNI Configuration in Cisco IOS

Cisco IOS Software-based PNNI node interfaces have autoconfiguration set by default. No more configurations are needed on this side as long as ILMI is configured on the links. ILMI is used for link signaling and parameter negotiation.

To complete your PNNI network setup and form a square, you configure two pnports: port 11.2 using VPI range 15 to 60 in the BPX-SES, and port 1:1.1:1 using VPI range 0 to 4095 in the MGX-8950. Both pnports go toward the Cisco IOS Software PNNI node, and the configuration is exactly as you did before. ILMI and PNNI should be up. VSI ILMI configuration in the BXM and AXSM slaves should be set.

The current PNNI network topology is shown in Figure 10-7.

To display the details of your PNNI network, display the PNNI database from the LS1010 using the command show atm pnni database (equivalent to the command dsppnni-idb in BPX-SES and MGX PNNI nodes). See Example 10-31.

Example 10-31. Using show atm pnni database

You can see the PNNI neighbors and the links between them, as shown in Example 10-32.

The links are in twoWayInside state.

You can see topology details for a specific PNNI node in the database using the command show atm pnni topology as shown in Example 10-33.
