Thanks a lot for your really fine statements about what one could/should do. >From what IŽve heard from you and what I read myself in the stevens book (tcpip illustrated) weŽll do the following: WeŽll start with RIP V2 since it's a easy to configure and enable routing protocol and it's available for all platforms easily. When looking at gatedŽs OSPF config file, I think it's something you might only need for a larger intranet. Portmasters will be in a separate segment and will get static routes to a default gateway which will be located in the "backbone" on the router. We don't have so much different routes, so that routing table updates every 30 seconds won't produce that much traffic, but we'll have an eye on that. Perhaps one more question. One of the features of RIP version II is the routing table update via multicast to only the routing machines in a subnet. What do I have to configure, if I want to enable multicast. I read, that there can be several hosts combined to different multicast groups. Is that figured out / configured automatically be the multicast protocol or do I have to configure multicast groups (the routing machines for example) by hand ???
