I have a setup which has multiple /20s(atleast 6) and i want to manage dhcp using FR 3.0.16. Now As i see I have to enter all the IP address in mysql for the FR to offer IP from when a DHCP request comes in.
Yes. FreeRADIUS doesn't implement a bad database itself (i.e. ISC does). Instead, FreeRADIUS relies on real databases to store the leases.
The total entries amount to 24576 so is it feasible to have frequent dhcp requests coming in, And as i see it searches in table everytime a request is coming.
25K leases is a very small amount. FreeRADIUS is being used in systems with 500K+ leases (using SQL), or millions of leases (using Redis cluster).
I might even have to throw in another sql query for DHCP request authentication, So is it a scalable solution?
Yes.
Or should i go for ISC(KEA also coming round the corner)?
I don't think I would recommend ISC for anything. I originally wrote the DHCP plugin for FreeRADIUS because I was frustrated with ISCs lack of flexibility, configurability, and it's fanatical insistence that databases didn't exist. Alan DeKok.
