The other side is where your customers are living. There are living real system and network managers who know what they are doing. I dont think they let slip RIP into your network.
ok
But there are also people who believe in windows, who believe it makes sense to use netbios packets in the internet. They dont even know their box is sending and receiving RIP.
I dont recollect any connection between Netbios and RIP. Am i missing something? Even if some application is leaking the RIP packets, why would they carry a tag in them? I thought it was a field rarely used in the implementations.
I dont believe in blocking internet packets, but I am shure it is a good idea blocking those RIP packets. They are definitely ment to stay in the local network. RIP was never meant for the internet. Only missconfigured router allow it to pass through.
And I cannot imagine anybody using RIP packets for SSH or something like that :)
