In this post, let me get some summary of Cisco BGP timers that you can find useful in real life as they reflect basic convergence and route propagation throughout a BGP routed network. I will try to present some of the timers on live example to the most possib…
最近遇到个问题,那就是win下的anyconnect无法获取用ocserv搭建服务的IPv6地址。
最近win7不知道做了什么设置,导致IPv6的无状态一直获取不到地址。 查阅相关资料最后重置的IPv6协议才解决。
关于模块预先配置 The pre-provisioning feature allows you to preconfigure interfaces before inserting or attaching a module to a Cisco Nexus 5000 Series switch. If a module goes offline, you can also use pre-provisioning to make changes to the interface configurations …
指导和局限 You can create up to ten checkpoint copies. You cannot apply the checkpoint file of one switch into another switch. Your checkpoint file names must be 75 characters or less.
最近使用NVI NAT出现了一点问题,可能是一个BUG。就是启用ip nat enable的端口up了NVI NAT的映射才会生效。反之,当设备重启Dialer1口最初为down的;或者Dialer1口地址释放重新拨号后NVI NAT就会失效。 此时解决方法就是重新配置NVI NAT即可生效。但是不是权益之计。
一般情况下将内网服务器地址(端口)映射到公网地址(端口),这样公网用户即可正常访问服务器,但是此时和服务器在同一内网的用户也访问公网地址(端口)将会不能正常访问。示意如下图:
