no ip routing 的问题

Question

我用Cisco Packet Tracer 做路由器的实验，想关闭路由器功能，总提示出错Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#no ip routing
^
% Invalid input detected at '^' marker.

Router(config)#no ip ?
access-list Named access-list
default-network Flags networks as candidates for default routes
dhcp Configure DHCP server and relay parameters
domain IP DNS Resolver
domain-lookup Enable IP Domain Name System hostname translation
domain-name Define the default domain name
forward-protocol Controls forwarding of physical and directed IP broadcasts
ftp FTP configuration commands
host Add an entry to the ip hostname table
name-server Specify address of name server to use
nat NAT configuration commands
route Establish static routes
tcp Global TCP parameters
Router(config)#no ip
不知道这是为什么，我用的是2621xm 路由器

你下面的语句不是列出了该命令的规则，规则里面没有当然不行了，你看看这个路由器是不是支持此命令，如果支持是不是你在配置模式不支持。
