拓扑结构
1、配置无状态自动获得IP地址(SLAAC)
Router0:
ipv6 unicast-routing ----开启ipv6路由功能后,才可以发送RA
interface G0/0
ipv6 address 2023::2/64
no shutdow
Router1:
interface G0/0
ipv6 address autoconfig
执行:
show ipv6 interface FastEthernet 0/0
查看接口状态
2、调整ND
Router0:
interface g0/0
ipv6 address 2023::2/64
no shutdown
ipv6 nd ra-interval 5 -----每5s通告一次RA
ipv6 nd ra-lifetime 1000 ----RA的lifetime
ipv6 nd prefix 2023::/64 5000 4000 ----修改valid time和preferred time
Router1#show ipv6 int g0/0
查看执行结果
3、不希望SLAAC
抑制RA消息:
ipv6 nd ra suppress
每日一更
问题描述
AR2200(V200R007)在什么情况下tcp会话会从几百秒快速降为1S?
解决方案
当tcp会话收到FIN和RST请求后会设置age-time时间为1
