RIP Issues - Cisco

Hey Guys,

I'm having an issue with RIP not "working" with all of the routes. This is in a DMVPN network and I have disabled Split Horizon on the hub router. We are unable to configure OSPF/EIGRP due to not all of our routers supporting them (We have 860's etc).

R2 is unable to see the 192.168.1.0 network

Configs are

R1

router rip

version 2

network 10.0.0.0

network 172.16.0.0

network 192.168.1.0

no auto-summary

R2

router rip

version 2

no validate-update-source

network 172.16.0.0

network 192.168.3.0

distance 121 192.168.1.252 0.0.0.0

no auto-summary

When I run a debug ip rip - I can see the network (192.168.1.0/24) that I want to get advertised however it never shows up in the rip database
