This blog was originally started to better help me understand the technologies in the CCIE R&S blueprint; after completing the R&S track I have decided to transition the blog into a technology blog.

CCIE #29033

This blog will continue to include questions, troubleshooting scenarios, and references to existing and new technologies but will grow to include a variety of different platforms and technologies. Currently I have created over 185 questions/answers in regards to the CCIE R&S track!! Note: answers are in the comment field or within "Read More" section.

The answer is yes when running PPPoFR

Example: R1 - R2

R1
__

username R2 password cisco

interface serial 0/1
encapsulation frame-relay
no frame-relay inverse-arp
interface serial 0/1.12 point-to-point
frame-relay interface-dlci 102 ppp virtual-template 1

interface virutal-template 1
ip address 10.0.0.1 255.255.255.0
encapsulation ppp
ppp chap authentication
ppp chap hostname R1
ppp chap password cisco

R2
__

username R1 password cisco

interface serial 0/1
encapsulation frame-relay
no frame-relay inverse-arp
interface serial 0/1.12 point-to-point
frame-relay interface-dlci 201 ppp virtual-template 1

interface virutal-template 1
ip address 10.0.0.2 255.255.255.0
encapsulation ppp
ppp chap authentication
ppp chap hostname R2
ppp chap password cisco
