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 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
