Re: ppp &hdlc [7:10737]
one glaring difference, I have heard that Cisco's hdlc is modified so it will not work with non cisco hdlc. PPP is PPP, you can attach a non Cisco router running pp to it and be successful.

Re: ppp &hdlc [7:10737]
I agree. PPP is a non-proprietary protocol and HDLC is vendor specific. If you are connecting to a non Cisco device, use PPP. If you are connecting 2 Cisco devices, use HDLC. HDLC is the default encapsulation on Cisco routers.

RE: ppp &hdlc [7:10737]
One difference between PPP and HDLC is that PPP supports authentication from PAP (password authentication protocol) and CHAP (Challenge Handshake Authentication Protocol). I believe that PPP runs over ISDN and HDLC doesn't (but don't quote me on that one, I'm not sure). -P Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=10766&t=10737 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: ppp &hdlc [7:10737]
Excellent point Preston. We can't forget multilink either. HDLC is also the default encap for ISDN: http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/dial ts_c/dtsprt3/dcdbri.htm#xtocid771414 HTH MikeN Network Engineer ""Preston Kilburn"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > One difference between PPP and HDLC is that PPP supports authentication from > PAP (password authentication protocol) and CHAP (Challenge Handshake > Authentication Protocol).

Re: ppp &hdlc [7:10737]
Both PPP and HDLC are encapsulation protocols on serial interfaces.But PPP is better than HDLC in 2 main points: 1- PPP supports multiple network layer encapsulation (IP,IPX,AppleTalk,...) while standard HDLC supports only IP encapsulation.[Cisco HDLC supports multiple network layer encapsulation]. 2- PPP suports both PAP and CHAP authentication protocols which provides a secure point-to-point session while HDLC doesn't support that.
