LAB: PPP AAA Authentication

requirements:

- r4 to authenticate R5 against the RADIUS server IP 155.1.146.100
-r5 to authenticate r4 against the tacacs+ server IP 155.1.146.200
- if both remote servers fail r4 and r5 should use local user db for authentication.
- use cisco to authenticate the remote servers.
- dont use global commands to define the radius server in r4.

fyi: r4 authenticates r5 using ppp and chap. r5 authenticates r4 using pap only.
