I am having difficulties understanding the following config as I don't have the ISDN equipment to test on :( I apprecate it if someone can explain it to me.

What interested me is the ppp and aaa authentication, are they correct? I created 2 groups (one tacacs+ server group name SANJOSE and a radius server group name ISDN. Can two groups have the same IP address?

All I want is allowing the users in group SANJOSE to access vty, aux, console and ISDN routers can authenticate only when the primary link failed.



enable password cisco


aaa new-model


aaa group server tacacs+ SANJOSE



aaa group server radius+ ISDN



aaa authentication login default group SANJOSE tacacs+ enable

aaa authentication ppp ISDN-remote group ISDN

aaa authorization login default SANJOSE group tacacs+ enable

aaa authorization network ISDN-remote group radius
