Chapter 3 Installing the Cisco XR 12406 Router
Connecting the PRP to an Ethernet Network
Figure 3-14 shows an example of the functionality of an Ethernet port. In this
example, you cannot access Network 2.0.0.0 through 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 3-14).
To access Network 2.0.0.0 from Router A, use an interface port on one of the 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 3-14).

PRP Ethernet Connections
Figure 3-15 shows a PRP RJ-45 receptacle and cable connector. 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 3-3
lists the signal-to-pin correspondence for the RJ-45 receptacle.
