作为一个运维，现在搞起了Ciso的BGP生意
在Cisco3650上定义VRF，结果报错，一头雾水啊，而且对Cisco也不熟悉啊。
#vrf definition mgmt
% Feature is not supported
没办法搜啊
解决方法如下：
sh license right-to-use
license right-to-use activate ipservices all
reload
license right-to-use activate ipservices all acceptEULA
reload
最后显示ipservices和lanbase都有就行了
#sh license right-to-use
Slot# License name Type Count Period left
----------------------------------------------------------
1 ipservices permanent N/A Lifetime
1 lanbase permanent N/A Lifetime
