Hi Team,
I was working on PPP over FR other day and somehow, I couldnt get it setup and working properly.
here is the setup :
R1 --- FR---R2, using physical interfaces.
R1 config:
username R2 password cisco
int virtual-template 1
ip add 10.1.1.1 255.255.255.0
encap ppp
ppp auth chap
int s 0/0
encap frame
frame int-dlci 102 ppp virtual-temp 1
R2 config:
username R1 password cisco
int virtual-template 1
ip add 10.1.1.2 255.255.255.0
encap ppp
ppp auth chap
int s 0/0
encap frame
frame int-dlci 201 ppp virtual-temp 1
Fr PVC status= UP
Virtualtemplate= Down, Which is OK as it will always be down/down
Virtual access 2 = Down
PPP status: LCP down, Closed.
Any inputs on this would be appreciated.
Regards,

If it doesn't work, turn debugging on ppp authentication.

Rack1R1#conf t

If the router's hostname isn't R1 and R2, you must send the hostname in chap with
ppp chap hostname
command.
BTW, I copied and pasted your config and worked here - the only thing I changed was adding the ppp chap hostname since my router's hostname wasn't R1 and R2.

Thanks Edison for the reply.
I think my hostname was the same as used in the UN/PW. let me go ahead check it right away and will rate the post. Thanks buddy !!

It has worked for me without the "PPP Chap hostname ". I dont know what I missed out earlier, but its working for me now. :-)
