Do routers by default listen and accept traffic from the Multicast ip address range 18.104.22.168 to 22.214.171.124 ?
Or do you have to be running a service on the router - such as OSPF for it to accept traffic from the multicast network range ?
For example in OSPF will all non DR routers accept traffic from 126.96.36.199 ?
What happens if a non DR router receives traffic directed to the DR ip address of 188.8.131.52 ? Does the router simply drop it ?
Many thanks in advance for any help on this.
