Hi All,
From my knowledge, the following are all WAN connectivity methods.
PPP
HDLC
MPLS
ATM
Is this correct?

OptionsColbyG Member Posts: 1,264I guess it depends on how you look at it. MPLS, FR, and ATM are WAN technologies, but all of those can utilize PPP/HDLC/Ethernet/etc. So you could have a PPP circuit which connects to an MPLS WAN, or PPPoA. So a lot of these things aren't mutually exclusive and can ride on top of each other.

Oh don't even get me started on this. I created a thread exactly discussing this fact about a month ago.....
It basically comes down to what Cisco or the CCNA wants you to know. If they ask on the test if an ethernet port is WAN, you better say NO!!!

Optionssuper22 Member Posts: 48 ■■□□□□□□□□I just configured this on my WAN serial link
router(config)#int S0
router(config-if)#ip address 192.168.1.1 255.255.255.0
router(config-if)#no shut
router(config-if)#encapsulation ppp
router(config-if)#end
Correct me if I am wrong but the default encapsulation is HDLC right?
Now what if I want it to go back to the default encapsulation..how do I do it aside from doing router(config-if)#encapsulation hdlc???
thanks:) -

Well, I guess if you do "no encap ppp" that will default back to HDLC.... -

Yes, that will also do it.
I'm assuming that you really were just guessing.
