updating a routing table entry

[Mike Tancsa]

I am trying to work around a problem, where a routing daemon (zebra) 
installs a subnet, that I then want to convert over to a connected route 
off an interface via ifconfig

e.g. on vlan2 I want to add an interface on the subnet 12.0.0.112/28. 
Before the ifconfig I see

# route get 12.0.0.112/28
    route to: 12.0.0.112
destination: 12.0.0.112
        mask: 255.255.255.240
     gateway: 192.168.1.1
   interface: vlan1
       flags: <UP,GATEWAY,DONE,PROTO1,PRCLONING>
  recvpipe  sendpipe  ssthresh  rtt,msec    rttvar  hopcount      mtu 
expire
        0         0         0         0         0         0      1500 
   0



In the case of the 12.0.0.112/28 network I guess i need to get the kernel 
and zebra to know that its not
flags: <UP,GATEWAY,DONE,PROTO1,PRCLONING>
but
flags: <UP,DONE,CLONING>

and via vlan2

Short of killing the routing daemon, doing the ifconfig, is there another 
way to do this ?

What about some ifconfig hackery ?  Is this not where it dies ?

         if (newaddr && (setaddr || setmask)) {
                 strncpy(afp->af_addreq, name, sizeof ifr.ifr_name);
                 if (ioctl(s, afp->af_aifaddr, afp->af_addreq) < 0)
                         Perror("ioctl (SIOCAIFADDR)");
         }


What if I added a check for a flag/param (e.g. -force)

         if (newaddr && (setaddr || setmask) && !FORCE ) {
                 strncpy(afp->af_addreq, name, sizeof ifr.ifr_name);
                 if (ioctl(s, afp->af_aifaddr, afp->af_addreq) < 0)
                         Perror("ioctl (SIOCAIFADDR)");
         }



Is there a better way to do it ?
