You can turn it off if you have no discontiguous network, but I always turn it off regardless and manually summarizing routes if necessary.

Turning auto-summarization off allows it to advertise the correct subnet mask. How would a router know where to send a packet if each router has a network with 10.0.0.0/8 and 20.0.0.0/8?

Turning it off allows it to recognize and advertise the correct subnet, 10.0.1.0/24, 10.0.2.0/24, 10.0.3.0/24, 10.0.4.0/24 and the same with the 20.0.0.0/24 networks. Hope this helped.]]> http://www.dslreports.com/forum/remark,22653972 Sat, 04 Jul 2009 14:06:21 EDT Re: Help with 5 router Frame Relay Config http://www.dslreports.com/forum/remark,22643290 anon : thank you very much, i never thought about turning off auto summary, if it's not too much trouble could you tell me why turning off auto summary works?

a picture is worth a thousand words:
