Hello,
In your R3 router config:
>interface Dialer1
>ip address 170.100.2.6 255.255.255.0
>no ip directed-broadcast
>encapsulation ppp
>ip ospf interface-retry 0
>ip ospf demand-circuit
>dialer remote-name 5 <--- Is it correct? 5 or R5
>dialer string 8358662
>dialer string 8358664
>dialer pool 1
>no peer neighbor-route
>ppp authentication chap
>ppp multilink
Best regards.
