I have a question about MAC-IP address binding. The problem is, today we use the PPPoE for DSL customers, but we will begin to give them "static ip address" for those who need it, I know we can sett the dynamic ip as static in the RADIUS server, but I will rater skill it the PPPoE is dynamic ip address assigment while the static must not be trough PPPoE but we just give them static ip address, so the customers can configure that ip address in their routers.
So back to my problem and question, the question is how can I bind the ip address for these users ?? We use IP-DSLAM (ATM Switch) in the PSTN. Our router is already configured for static ip in the separate VLAN, so I am not sure how can I bind the ip address because let`s say we give one user the ip address 18.104.22.168 and we will this user be able to use ONLY this ip address, so EVEN if he tries to sett 22.214.171.124 than he must not be able to use this ip address, but the only one we gave him.
I was thinking about static ARP table where we bind ip address to an MAC address of the IPDSLAM switch port, but this is not a solution because he can than just pick up another ip and put it manually in the router, so this is not good chooice.
Any great suggestions ?? how these things are handled in case static ip address assigment anyway ??
I've got an answer:
DHCP is the only option. (policy)
"If someone assign an ip statically they will create problems for themselves, because
the ip will not get renewed and "soon" assigned to another customer"
So I think you might use DHCP exclude address on your server , and use the same policy as stated: if someone use another IP address they will create problems for themselves :)
I belive that not every customer wants fixed ip, but of cource you can use the range command, but that depends on you vp vc assignment :)
