PRP Port Connection Guidelines
Figure 2-21 shows:
• You cannot access Network 2.0.0.0 from Ethernet port (E0) on the GRP in
Router
A. You can only access Host A, Host B, and Router C, which are in
Network 1.0.0.0 (see dotted-line arrows).
• To access Network 2.0.0.0 from Router A, you must use an interface port on
one of the line cards (a POS line card in this example) in Router
A. Data from
Router
A is routed through Router B and Router C, to reach Network 2.0.0.0
(see solid-line arrows).
