We currently use a 7301 router as an LNS and have it configured to use a local IP pool and dynamically assigns an IP address to connecting DSL modems. We would like to start providing a static IP to a username that autheticates to a radius server. I was wondering what the LNS config should have to support receiving an IP address from the radius and not using the local pool on the router. We want the LNS to take the IP address that radius would provide and send that to the dsl modem.
If anyone could help with what config items are needed to support this I would appreciate it. What we are seeing now is radius authenticates the user, sends the IP address in the FRAMED-IP but the LNS picks an IP address from the local pool and assigns it. Just wondering what we are missing here to make the 7301 assign the ip from radius.
aaa authentication ppp vpdn local group radius
aaa authorization network vpdn group radius local
aaa authorization configuration default group radius
Thank you for the suggestion. I added debug radius and this is what was returned. instead of the user getting the IP y.y.y.20 the next available IP in the DHCP local pool y.y.y.13 is assigned to the user instead.
Any other suggestions now that you are looking at ths output?
