Description dbodnarc 2017-05-22 11:38:37 UTC 
Description of problem:
Dracut DHCP is still failing to recognise rfc3442-classless-static-routes option. Occurs only when DHCP booting on network offering only classless static routes.
This issue was previously described in Bug #1260955 but it looks that the customer still hits the mentioned bug.

Version-Release number of selected component (if applicable):
RHEL-7.3 installer (rhel-server-7.3-x86_64-dvd.iso)

How reproducible:
The steps to reproduce the bug are to boot into the initramfs image included in the rhel-server-7.3-x86_64-dvd.iso in a DHCP environment with option rfc3442-classless-static-routes.

Actual results:
When the system boots, only the route to the local gateway is present (all rfc3442-classless-static-routes (DHCP option 121) are being ignored.

Expected results:
rfc3442-classless-static-routes (DHCP option 121) are available when the system boots.
