看到这样一句话:
The router decrements the TTL value by 1 (if the packet is held in the
router’s queue for more than a second, it should also be decremented by the
number of seconds it was held).
意思是:当数据包经过路由器时,TTL值减一,前提是TTL>2。
more than 在这里指>= ,还是这句话有问题呢?
路由设备上的traceroute,第二次发送的就是TTL=2的数据包,按说TTL=2是会被正常转发的。 |
