[SOLVED] DHCPD: how to add multiple static routes to subnet

koloth · 10-18-2017, 08:33 AM

Hello,
Working on Centos 6.9 running isc-dhcpd-4.1.1-P1, I'm trying to make the dhcp server daemon serve more than one static route for a dhcp request.

I have configured the server to understand option 121 like that:

Code:

rfc3442-classless-static-routes code 121 = array of unsigned integer 8;

I have also added something like the following to my subnet:

Code:

option rfc3442-classless-static-routes X, X,X,X,X, X,X,X,X;
option rfc3442-classless-static-routes Y, Y,Y,Y,Y, Y,Y,Y,Y;

However my dhcp requests only get the second route (the Y one).

Any ideas?

What happens if you do the following?

Code:

option rfc3442-classless-static-routes X, X,X,X,X, X,X,X,X, Y, Y,Y,Y,Y, Y,Y,Y,Y;

Works like a charm!
