ppp chap authentication

jtdk985

hey guys,

trying to do this lab where it wants to use chap authentication with ppp, can someone please verify this order of commands to say they are correct in enabling chap? this is the order from two different routers:

Ranet-BR2(config-if)#int s0/0/0
Ranet-BR2(config-if)#no sh
Ranet-BR2(config-if)#clock rate 64000
Ranet-BR2(config-if)#ip add 172.20.1.234 255.255.255.248
Ranet-BR2(config-if)#encapsulation ppp
Ranet-BR2(config-if)#ppp authentication chap
Ranet-BR2(config)#username Ranet-BR1

Ranet-BR1(config-if)#int s0/0/0
Ranet-BR1(config-if)#no sh
Ranet-BR1(config-if)#ip add 172.20.1.233 255.255.255.248
Ranet-BR1(config-if)#encapsulation ppp
Ranet-BR1(config-if)#ppp authentication chap
Ranet-BR1(config-if)#exit
Ranet-BR1(config)#username Ranet-BR2
Ranet-BR1(config)#
Ranet-BR1#

I thought chap had to have matching usernames AND passwords? so if im right, the lab is incorrect, and the usernames are wrong, and its missing passwords as well.

thanks for the confirmation or correction

Nope thats right. The username is the name of other router.

ok i can see where i misread on that, now does it require passwords?

i guess it does, the lab states no password is necessary, so i just added one and its connecting fine. thanks!
