Verify / troubleshoot RIP configuration on PC6224

Question

I am trying to configure RIP between a PC6224 and our firewall (Watchguard XTM510) to test if we can use RIP for simple, but automatic failover situations. I've configured the 6224 and our firewall with RIP, but no routes are being exchanged. My first thought was that our firewall was misconfigured, Watchguard took a look at the configuration and I was being told that the firewall is not receiving any route / RIP updates. So my next step is to call in some help of Dell support to verify the RIP configuration on the 6224 as well. show ip rip: RIP Admin Mode................................. Enable Split Horizon Mode............................. Simple Auto Summary Mode.............................. Disable Host Routes Accept Mode........................ Enable Global route changes........................... 1 Global queries................................. 0 Default Metric................................. Not configured Default Route Advertise........................ 0 Show ip rip interface vlan 99 Interface...................................... vlan 99IP Address..................................... 172.16.99.254Send version................................... RIP-2Receive version................................ RIP-2RIP Admin Mode................................. EnableLink State..................................... UpAuthentication Type............................ NoneBad Packets Received........................... 0Bad Routes Received............................ 0Updates Sent................................... 22091 The firewall is directly connected to the 6224. RIP communication should go via VLAN 99. Direct communication via VLAN99 is possible.... VLAN 99 configuration: interface vlan 99 routing ip address 172.16.99.254 255.255.255.0 ip rip exit show ip route rip all is empty. Is there a way to troubleshoot RIP communication further? I my opinion, this configuration should work...

Just an update. I trying to get things going with the vendor of our firewall. They tell me that the firewall is not receiving updates on VLAN 99, but I am not convinced since the Dell configuration is simple and the show commands show information about updates are being send.

The firewall Vendor verifies the configuration and told me that the config should work for VLAN 99. One thing I am concerned about is that at the Dell side, I've no neighbours configured. RIP V2 sends updates with multicast instead of broadcast so how does the switch know where to send the update to?

The firewall is using RIP version 2 as well. That is not the problem I think. There is no configuration command like ip rip neighbor or so? RIP V2 sends updates via multicast, but if there are no members added to the multicast list... Not one neighbor receives updates... That the point I am most concerned at the moment!

It's working! Thanks a lot. This is really a breakthrough for our dynamic routing. Ripv1c has the features of RIPV2 but sends update to broadcast instead of multicast? For example, VLSM is supported?
