Hi Sam,
R4 is configured to challenge R5 inbound and outbound, so it does need the
username there. You can tell because it has the "ppp authentication chap"
line in it, which tells the router to authenticate both ways. R5 does not
challenge R4 when it calls R4. You can tell because it has the "ppp
authentication chap callin" line. When R4 authenticates R5 and determines
it is a callback request, it will hang up and call R5 back. Then R5 will
authenticate R4 as "ROUTER4".
Thanks,
Mike

Hi Group
In R4, I cannot see why we have to configure username and password for R5
since R5 is not being challenged by R4.
Is that necessary ?
BTW I cannot test it cos my ISDN sim isgoing to the bin in 10 seconds.
TIA
Sam
