My CCNA just expired today after never really using it. I'm trying to refresh my knowledge (because I just happened to get a job where I will use it).
I said it in the title. It's a 2 router topology connect by a serial port. I encapsulated both interfaces in PPP, and purposefully set my hostname:West router's interface to 184.108.40.206/28 and hostname:East router to 220.127.116.11/24. Then did a show interface on each router to see the difference in output. But everything was the same; up and up.
I can ping both ways! Did I completely forget how this should work, or is this a packet tracer error? Or, is this a PPP thing that I forgot about
btw, show ip route shows routes to each network, directly connected (I don't have any routing protocols running either)
Really, the topology looks like this 0<------>0 That's it. No other configurations.
edit: Just changed encapsulation back to hdlc. I'm no longer able to ping. What gives?
