Adding/Deleting/Modifying routes   
Hi,

I am trying to implement a simple API to add, delete and modify routes along with specifying outgoing interfaces (if 
possible, for cases where I have more than one interface with the same IP address).

I looked at the route utility and it seems to use raw sockets for programming routing table. Is that the recommended 
approach? In linux I think I was using Netlink/Dgram sockets to perform this function. Not sure what works with io-pkt.

Thanks,
Santosh

Routing sockets (AF_ROUTE) are recommended whch is what the
'route' utility uses.

Hi Sean,

The route utility uses, RAW socket with AF_ROUTE/PF_ROUTE family and it seems to use rtmsg to perform the final setting.


Q: Do I have to use rtmsg and RAW socket for my implementation or can I use ioctl? Does only RAW socket work or DGRAM 
works as well?

Thanks,
Santosh

It has to be AF_ROUTE, SOCK_RAW.

Re: Adding/Deleting/Modifying routes   
In Linux you can program with netlink and route socket both. Although netlink is a protocol too but I only LInux uses it
 as interface between userland and kernel.
In BSD only route socket available I think.
