Can't open the srv6 example correctly. about ipmininet

[jadinm]

Hello,

Could you tell me which version of FRR you are using with the following command ?

$ zebra -v

And the version of ipmininet that you use with the following command ?

$ pip show ipmininet

Can you execute the examples simple_ospf_network and simple_ospfv3_network or does it raise the same issue ?

@jadinm Hi ,Thanks for your reply and here is my terminal log, simple_ospf_network works well but simple_ospfv3_network raise the same issue

Ok so your problem is that you are using Quagga and not FRR

The version of ipmininet 0.9 supports FRR 7.5 but not Quagga
There are slight differences in the configuration files and this is one of them

Thanks for your help!
