Hi,
I am doing a network simulation using Cisco Packet Tracer. I could not solve how to do CHAP over TACACS+ server. The situation is as follow:
Configure PPP Authentication Protocol on the following devices as listed herewith :-
Hostname PPP Authentication Authentication key Username Password
-------- ---------------- ---------------- -------- --------
Branch#1 TACACS+ ENT-AAAKEY123! Admin admin123!
Partner-RTR#1 TACACS+ ENT-AAAKEY123! Admin admin123!
I have 2 routers connected each other on Serial. Router Partner are connected to TACACS server. My configuration is as follow on both routers:
aaa new-model
!
aaa authentication ppp default group tacacs+ local
!
username Admin password 0 admin123!
!
interface Serial0/0/0
ip address 203.127.66.2 255.255.255.252
encapsulation ppp
ppp authentication chap
!
tacacs-server host 10.111.111.242 key ENT-AAAKEY123!
!
The only problem i got is when I used 'ppp authentication chap' the protocol will go down. I already configured all the AAA on the server. Please help me.
