be careful when saying that passive interfaces block updates on an
interface, it actually only blocks OUTBOUND updates on that interface, but
still allows INBOUND updates

its running RIPv2, take a look at his configuration on the serial interfaces,
there are ip rip send/receive version 2 commands

make a habit of trying to problem solve using the routing table...
your next hop for those addresses above is 137.6.1.10, refer back to your
configuration you will notice that it is the serial1 interface of your R2
router, then take a look at your router rip configuration...
you used passive-interface on serial0, instead it should have been on serial1
