9. Test by pinging each network. Notice how you can only do two routes at a
time. This is because you only have two b-channels. You would need to add
more to do more at once.
Challenge Lab or Supplemental Activities:
1. Repeat the lab using Class “B” addresses.
2. Repeat the lab using Class “A” addresses.
3. Try using PAP as an encapsulation for PPP. Try HDLC.
So what have I learned here?
In this lab you have learned how to set up an ISDN BRI connection using the ADTRAN
between four routers. The key here was the PPP multilink command. You also got some
good training on how to break a large project down into smaller steps.
Guest Router Name Derivation
Geoffrey Osowski and Wilson Tang were accountants who worked for CISCO
(yes…them!). They were charged with computer-related crimes when, being
accountants, they illegally issued almost $8,000,000 in CISCO stock to themselves. They
each received 34 months in prison, 36 months of probation, and restitution of almost
$8,000,000. The moral of the story is don’t try this at home!
