Hi,

Does option 249 on IOS DHCP server work? if yes, how does the command syntax look like?

Thanks a lot!

Re: dhcp option 249 on IOS

You can use DHCP option 33 on 3750 IOS to push a static route for a subnet.

Option 33 will allow you to insert static routes on your DHCP configuration but it will only accept classful networks and it limited to allow only two networks. The way to configure this is:

config t

ip dhcp pool

option 33 ip 172.16.0.0 172.18.18.1 172.17.0.0 172.18.18.1

I hope you find this information useful.

Re: dhcp option 249 on IOS

Hi, Joseph,

I tried option 33 before. However, the route on my Win XP machine looks like this:

172.16.0.0 mask 255.255.255.255 172.18.18.1

not usable at all.

If IOS propagates a host route to client, it's fine.

Thanks anyway.

Jonathan
