Hello
I have a problem where I don't receive RIP Updates from upstream devices 192.168.x.20 and 192.168.x.21. This is on a 3750 L2 Switch with IOS c3750-ipservices-mz.122-25.SEB4. RIP only seems to be Sent/Recieved on one Interface (VLAN 4). Basic config, debugging and show output below.
interface Vlan2
ip address 192.168.x.1 255.255.255.128

interface Vlan3
ip address 192.168.x.129 255.255.255.128

interface Vlan4

You need to configure VLAN2 and VLAN3 for RIP routing.
If you look under 'show ip protocols' you will see that the router is only routing for the 10.0.0.0 network with RIP.
I would also do a 'no auto-summary' as well.
