This is where my skills are not great (regex) most other areas I can work with. Ultimately I am happy to pay someone to help write the little bit of code that does this. I do need to cope with Netmasks from /32 to /24 so a few switch cases.
It shouldn't be difficult.
Alternatively if someone can provide a few pointers on that bit I can probably build from there.
If you have:
Cisco-AVPair = "ip:route=1.2.3.1 255.255.255.240"
Step 1, split it into pieces: if (&Cisco-AVPair =~ /ip:route=([^ ]+) ([^ ]+)/) { This matches the "ip:route" prefix. It then matches non-space data, then a space, and more non-space data. As per the FR documentation, the first match goes into %{1}, and the second into %{2}. As there are only a limited number of net masks, you can expand the net mask, and switch over it (inside of the "if" block from above) switch "%{2}" { case "255.255.255.255" { update reply { Framed-Route = "%{1}/32" } } case "255.255.255.254" { update reply { Framed-Route = "%{1}/31" } } case "255.255.255.252" { update reply { Framed-Route = "%{1}/30" } } ... etc... # and the "catch all" case, just mash it to /28 case { update reply { Framed-Route = "%{1}/28" } } } A little verbose, but it should work.
