Difference between ICND1 and ICND2 regarding WAN...

[ICND1]
Configure and verify a basic WAN serial connection

[ICND2]
Configure and verify Frame Relay on Cisco routers
Troubleshoot WAN implementation issues


The description in ICND1 is pretty ambiguous. "A basic WAN serial connection". What kind of WAN serial connection is basic?

I would think HDLC for ICND1 and everything else for ICND2.

I thought PPP was also in ICND1?

HDLC is the default... I think (99% sure). There wouldn't be a need to configure it as it's the default for the Serial WAN links.

I took the ICND1 as: know how to config by "encapsulation ppp" and "encapsulation hdlc" (if someone has it on something else) then check with show interface or show ip interface brief on that interface. ICND2 is really knowing how to do Frame Relay and setting that up not just knowing its definition.

Configure may just mean configure and ip address and a clock rate and see if it comes up/up.

HDLC is default for all serial interfaces.

ICND1: PPP, HDLC
ICND2: Frame Relay, PPP, HDLC

mapletune

agree with above

The IT Guy

I agree with YFZblu. You may also get a brief intoduction to X.25 and ATM before getting to the Frame Relay theory and Configurations in ICND2.

I love this thread as it applies directly to my cisco iv class. all about Frame Relay, PPP and HDLC..basically all layer 2 WAN protocols which is where WAN protocols reside: Layer 2! Are WAN protocols Layer 1 as well?

No. Layer 1 is physical. How do you apply protocols to voltages on a cable or flashes of light down a fiber.
