my design is as followed: R1

R0 | \ | \ | \ R1 ___ R3

I can't set a static route（R1----R3---R0）. it is Directly from R1 to R0.

sorry，it is R2

R0 | \ | \ | \ R1 ___ R3

Hi, Are you using this repository's code ? The code you quote is not from this repo it seems.

qazxswedc123654 commented 5 years ago

I'm not using this repository's code.I changed something according to my own topology.

teto commented 5 years ago

hi could you share the code ? from a git repository for instance. What version of ns3 do you use ? Could you compile this repo without modification ?

qazxswedc123654 commented 5 years ago

This is the complete code (I haven't done it yet), I just need to complete a simple Ns3 topology (using global and static routes at different nodes) the version is3-28

qazxswedc123654 commented 5 years ago

It seems that it does not go R1---R3---R0 during the running process ( R0 R1 R3 has a P2P link connection with each other), and it is (R1----R0), What is the reason?

qazxswedc123654 commented 5 years ago

Hello, I don't know if you are still there, can you give me some advice?

Hello, I don't know if you are still there, can you give me some advice? I want to know how to determine the value of 1 in sstaticRouting1->AddHostRouteTo (Ipv4Address ("10.1.1.13"), Ipv4Address ("10.1.1.10"), 1); Because I am a newbie, I don't know anything about this code.

You an have a look at the documentation: https://www.nsnam.org/doxygen/classns3_1_1_ipv4_static_routing.html#ae96452233179689167e57b49b4339005 the third parameter is the interface address.

Please answer these basic questions:

which version of ns3 ?
what are you trying to achieve ?
if possible, point me at the code please
