[Ndn-interest] [Nnd-interest][mini-NDN] Topology configuration problem

[Pengyuan Zhou]

Hi all,


I met with the problem that, only one directional of the added links can ping.

For instance, if I add link a:b bw=100, only b can ping a. Sometimes neither can ping the other.

A sample screenshot of the problem as below. As you can see, u5 and e5 are linked, however, only e5 can ping u5, not the other way.

I'll appreciate for any advice.


Thank you.

BR,

Pengyuan
