hi all, suppose i have 4 routers connected via frame-relay with only their physical interfaces. R1 R2 R3 R4. R1 is the hub where R2, R3, R4 are spokes. Now at R1 i want to configure policy such that the networks learned via R3 are not propagated to R4. I am running RIPv2 on my network. i want to filter updates based on neighbours so kindly let me know how can i do it. i dont want to use any tunnels, nor any subinterfaces, now is there any way to do it ?? in my quest of doing it using several methods i found that cisco has tried to make sure it CANT be done :-), any 1 knows how to do it ?
