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
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).

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.
