How to know number of subnets on large Campus network across city
-
I have an application that a vendor provides that uses Multi-cast or IGMP that that allows applications to send messages on a broadcast group. When other applications listen to this group, they can also see messages from other terminals. I don’t know if Multi-cast or IGMP is enabled and don’t want it enabled. I want to use vendor’s Multi-cast application. If any of your computers are running in separate subnets, the issue is that most network routers/switches do NOT forward multicast traffic to other subnets.
How do I explain we are on the same or different subnet on a large multi-campus network across a city? How do I know how many subnets and how many of these vendor’s multi-cast applications I’ll need to install. I need on each side of the subnet.
Vendor’s Multi-cast application is a very lightweight application that run as a service. I’ll need to install it on a server preferably, or a computer that does NOT run a vendors main product on each side of the subnet. There will be a hosting computer – normally the SQL server. The application gets installed and configured. For each of the subnets that require multicast, I will install the vendor’s Multi-cast application on a computer in that subnet. -

Also not sure what you mean by IGMP sending messages to a broadcast group. So please, let us know, the post is a little confusing to me.
So without knowing what you're trying to do: If the application allows you turn off multicast and use unicast instead, you can do it that way. If not, you'll have to enable ip multicast routing on your routers and configure it there and possibly IGMP-snooping and multicast vlan registration if you're using vlans.

The protocol information was just background from the vendor and how their applications ia used.
I'm only asking if you could help me with determining submits on city multiple geographic location network. They want this application on both sides of subnet or help determine if only one subnet.
I just want confirm subnet setup on production network.
Than you -

Than youYou should be able to see your routing table on the routers. Those should reveal all the networks that are reachable from your network.
