Dear all,

I have RIP (Zebra) setup in my SPLAT. But then when the route change,
SPLAT give out some error about Address spoofing. 


Subnet A
   |
 SPLAT - Subnet B
   |
Subnet C(External, Default GW)

Say, the route was coming from Subnet A original learnt from RIP. Then
the connection is broken and the route now goes to the default GW. The
Firewall sent out message about Address spoofing on the External
Interface (Subnet C). I disabled the Anti-Spoofing and it works. But are
there some better method that I can use with Anti-Spoofing turn on?

Best Regards,
