Mikrotik does not respond on 224.0.0.5 pings. Why?

RouterOS Forwarding Protocols
1

Good night!

I made simple ospf scheme: http://wiki.mikrotik.com/wiki/OSPF-examples#Simple_OSPF_configuration

All is working, i can see all neighbors and all routes.

But i am trying ping 224.0.0.5 and 224.0.0.6 and cann’t see answers.

Is it normal? Can you help me and try to ping this addresses in your ospf-networks? And can you see answers?

Thanks!

ps: In equal network on cisco-devices all routers respond on pinging 224.0.0.5
