The Unicast routing table is fine , I have checked all OSPF enabled and routes are advertised correctlyI am wondering if R3 is suffering from RPF check , why the rp mapping appeared ? R3#sh ip rpf 9.9.0.7RPF information for ? (9.9.0.7) RPF interface: GigabitEthernet0/0.34 RPF neighbor: ? (9.9.34.4) RPF route/mask: 9.9.0.7/32 RPF type: unicast (ospf 9) Doing distance-preferred lookups across tables RPF topology: ipv4 multicast base, originated from ipv4 unicast base R6#sh ip rpf 9.9.0.7 failed, no route existsR6#ping 9.9.0.7 souR6#ping 9.9.0.7 source lo0Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 9.9.0.7, timeout is 2 seconds:Packet sent with a source address of 9.9.0.6 !!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 8/20/52 ms
