This challenge involves the configuration of the S0 port on a router. The objectives of this challenge are to:
> enable # config t (config)# username fred password bert (config)# int s0 (config-if)# ip address 138.199.17.1 255.255.255.248 (config-if)# no shutdown (config-if)# description students (config-if)# encapsulation ppp (config-if)# ppp authentication chap (config-if)# clock rate 56000 (config-if)# carrier-delay 8 (config-if)# bandwidth 198 (config-if)# no ip route-cache (config-if)# no fair-queue (config)# end
