RIP multicast problem

Tue Oct 19, 2021 5:58 am

I am studying for the CCNA test so I bought a refurbished Cisco 2911 on Amazon to play with my main home router (Mikrotik Audience running 6.49). It's hooked like this:

WAN <> Audience <> TP-Link Smartswitch <> Cisco 2911 <> laptop

The smart switch handles VLAN's so the Cisco is hooked up to VLAN40 configured in my Tik.

Even after installing the multicast package, the two routers will not communicate routes via multicast. The only way i can get it to work is to configure the Cisco as a "neighbor". According to the manual, https://wiki.mikrotik.com/wiki/Manual:Routing/RIP:
Normally there is no need to add the neighbors, if multicasting is working properly within the network. If there are problems with exchanging routing information, neighbor routers can be added to the list. It will force the router to exchange the routing information with the neighbor using regular unicast packets.
So obviously multicasting is not working properly but I have no idea where to go from here. Here is my RIP config:
/routing rip interface
add receive=v2
/routing rip neighbor
add address=192.168.40.100
/routing rip network
add network=192.168.5.0/24
add network=190.168.40.0/24

This just turned out to be a typo in an ip address that my up too late brain didn't catch until now.

add network=190.168.40.0/24 should have been add network=192.168.40.0/24
