哪个路由器端口地址应响应传输消息中超出生存时间的情况?
假设以下情况:
PC --- |aa RTR1 bb| --- |aa RTR2 bb| --- |aa RTR3 bb| etc
每个 |aa rtr bb|
都是一个具有两个端口 aa
和 bb
的路由器。
当我从 PC 进行跟踪路由时,哪个路由器端口地址应响应传输消息中超出的生存时间?
我似乎记得被教导将路由器视为与端口一样多的部分,因此在我的场景中,当 aa
将数据包转发到 bb
并减少TTL为0,则为失败消息中aa
端口的地址。我正在努力寻找明确的答案。
Given the following situation:
PC --- |aa RTR1 bb| --- |aa RTR2 bb| --- |aa RTR3 bb| etc
Each of the |aa rtr bb|
is meant to be a router with two ports aa
and bb
.
When I do a trace route from my PC, which router port address should respond with time to live exceeded in transit message?
I seem to remember being taught to think of the router as being in as many parts as ports, so that in my scenario when aa
is forwarding the packet to bb
and decrements the TTL to 0, it will be the address of the aa
port in the failure message. I am trying to find the definitive answer.

由于每个路由器使用
aa
而不是使用bb
向您发送 ICMP 数据包,因此它发送的数据包将具有aa
的地址,而不是>bb
的。路由器生成 ICMP 数据包并将其发送给您。数据包将具有的源地址是该数据包发送的源地址,
aa
的地址。Since each router sends you the ICMP packet using
aa
and not usingbb
, the packet it sends will haveaa
's address and notbb
's.The router generates an ICMP packet and sends it to you. The source address the packet will have is the source address that this packet is sent from,
aa
's address.
