PPP Over Frame Relay

PPP Over Frame Relay last time I looked was a CCIE subject, I'm guessing because of the use of Virtual Templates that you will see later.

R1

1) Define PPP authentication information:

username R1 password 0 CCNP
username R3 password 0 CCNP


2) Map the DLCI to a Virtual Template:

frame-relay interface-dlci 123 ppp Virtual-Template1


3) Set up the Virtual Template:

ip unnumbered Serial0/0.123
ppp chap password 0 CCNP


R3:
(Its pretty much the same)


username R1 password 0 CCNP
username R3 password 0 CCNP


2) Map the DLCI to a Virtual Template:

frame-relay interface-dlci 321 ppp Virtual-Template1


3) Set up the Virtual Template:

ip unnumbered Serial0/0.321
ppp chap password 0 CCNP
