I'm trying to understand how auto summarization works in RIPv2. I understand that it is enabled by default. Does this mean that if I have a subnet mask (lets say 26) that is greater than the class subnet mask (24), that it will automatically summarize it down to the class mask (24)? And if so, isn't this an issue on discontiguous networks where a router in the middle would summarize all the subnets up to a classful netmask?
