version 2

network 192.168.1.0

passive-interface default

no passive-interface eth0


Hope to help

router rip

no passive interface default


you need to change the above to "passive interface default"


then do as Guiseppe suggested or leave your neigbor command in.


With the neighbor command updates are unicast rather than multicast. If you use "no passive interface ethernet 0" the updates will be sent as multicast - 224.0.0.9.
