Route addition in vista

J

Jothi

Hi All,
I am using Windows Vista for my network application development under
administrator login(full access). I am trying to add a route to the
exisisting route table using CreateIpForwardEntry API.
I am getting following error.
"160 - One or more argument are not correct." .
But From command prompt I was able to add/delete the route uusing route

commands.

Anybody have idea on solving this issue.


the source is here


BOOL Add_Route_x( DWORD destination,
DWORD gateway,
DWORD mask,
DWORD metric,
int row_number,
DWORD index,
DWORD fwdType)

If anybody know how to solve this issue, please let me know. Parallely
I will change parameter details and try.


I am not getting meaning of

sub-interface (where the interface LUID and subinterface LUID are the

Please explain if anybody understood.

No, I don't. However, it would never occur to me to post Vista questions to
an XP newsgroup.

The routing metric in Vista is the sum of the interface metric and the
routing metric. You can query them individually with netsh\itf\ip.
A workaround can be to set the metric to 21.
