Cisco Multiservice Switching Networks

The objective of this chapter is to bring up the network shown in Figure 10-1. First, the four PNNI nodes are configured to set up the PNNI network.

Two external Cisco 7500 routers will be connected through the network using switched virtual circuits (SVCs) and Soft Permanent Virtual Circuits (SPVCs). Connectivity to an RPM-PR-based CPE in the MGX-8850 will also be configured using SPVCs.

Your PNNI network is a single peer group (SPG) network at level 64. This means that the first 64 bits or 8 bytes form the peer group ID (PGID). The PNNI node's ATM End System Addresses (AESAs) are chosen so that there's a unique and common peer group ID at level 64. See Figure 10-2.

For the purposes of this and the following chapters, AESAs with International Code Designator (ICD) format have been chosen, with a bogus ICD of 0x0000.

As shown in Figure 10-2, the number in the switch platform name is included in the switch ATM address for ease of identification.
