[ns] routing outside the subnet.

[sxroy1]

under the dsdv.cc file there is a function which drops the packet if its 
destined for outside the given subnet, the function is as follows:
DSDV_Agent::diff_subnet(int dst) 
{
        char* dstnet = Address::instance().get_subnetaddr(dst);
        if (subnet_ != NULL) {
                if (dstnet != NULL) {
                        if (strcmp(dstnet, subnet_) != 0) {
                                delete [] dstnet;
                                return 1;
                        }
                        delete [] dstnet;
                }
        }
        //assert(dstnet == NULL);
        return 0;
}
 can any one give me any idea abt how to avoid this and add the route in the 
table so that routing to other subnets could be possible ?

any help would be really appriciated. thanks
