Hello, I have been trying to figure out a response for the following questions, but I have only suppositions and I haven't found (yet) a document that accurately talks about. So I am asking here.
Why wouldn't a router be authorized to send Router Sollicitation messages? Moreover, why couldn't a router autoconfigure its egress interface based on Router Advertisements received on this interface? The same question for autoconfiguring the prefix it advertises on its subnets. The only answer that comes in my mind is because an attack over these messages could render not only a host unreachable, but maybe a whole subnet. But apart this, is there really any other reason for not allowing this? Thank you in advance for the answers. Best regards, -- Silviu
