Re: Multiple network interface & routing question


Thanks,

It looks reasonable, I'll give it a try.

Hi All,

I'm using the bsd sockets code and I have more than one interface. I am seeing that when one interface has to reget an address via dhcp then I get problems using the other interface.

Looking through the code it appears there might me a problem with the routing table. The dhcp code calls cyg_route_reinit() in a couple of places - do_dhcp_down_net() and bring_half_up() which are called whilst obtaining an address. The cyg_route_reinit() function seems to just empty the routing table regardless of interface.

Could this be my problem or am I looking in the wrong place? Anyone got any code for removing all routes for a specific interface only?

There is a patch for that somewhere in ecos-patches, probably in the last year. Although it looked O.K. i was not convinced it would work in all situations. Why did the original author of the DHCP client not do something similar?. I don't have a dual interface device so i cannot test. So i would be interested in your comments about the patch.

Andrew
