Cisco Systems Cisco 12008 manual PRP Ethernet Connections, Using the Ethernet Port on the PRP

Connecting Route Processor Cables

Figure 3-12 shows an example of the functionality of an Ethernet port. In this example, you cannot access Network 2.0.0.0 via the Ethernet port (ETH0) on the PRP in Router A; you can only access the hosts and Router C, which are in Network 1.0.0.0. (See dotted arrows in Figure 3-12.)

To access Network 2.0.0.0 from Router A, you must use an interface port on one of your line cards (in this example, a Packet-over-SONET (POS) line card in Router A) to go through Router B, through Router C, and into Network 2.0.0.0. (See solid arrows in Figure 3-12.)

PRP Ethernet Connections

Figure 3-13 shows a PRP RJ-45 receptacle and cable connectors. The RJ-45 connection does not require an external transceiver. The RJ-45 connection requires Category 5 unshielded twisted-pair (UTP) cables, which are not available from Cisco Systems, but are available from commercial cable vendors. Table 3-7 lists the pinout for the RJ-45 receptacle.
