Well, From http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/np1_r /1rprt2/1ripadr.htm#xtocid12 :
ip classless At times the router might receive packets destined for a subnet of a network that has no network default route. To have the Cisco IOS software forward such packets to the best supernet route possible, use the ip classless global configuration command. To disable this feature, use the no form of this command. Regarding subnet zero, the IOS didn't used to let you assign an address that was part of subnet zero. It wasn't allowed because it could create an address that was the same as the subnet address. Here's a link from cisco with more lovely info about that and the all one's subnet: http://www.cisco.com/warp/public/105/40.html -----Original Message----- From: Arnaldo Gomez [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 13, 2002 1:45 PM To: [EMAIL PROTECTED] Subject: Ip subnet Zero & Ip classess [7:35340] Can someone give a gerneral explanation on these two commands? ip subnet-zero ip-classless What do they do and why would you use them?
