How to use veth pair interface for test?

[dingrui37]

I add a pair of veth(vethHR<--->vethRH) and set vethRH to another netns，then use smcroutectl to add multicast route, but it does work， why?

ubuntu@OptiPlex-3000:~$ sudo smcroutectl add vethHR 239.0.10.1 vethH1
smcroutectl: ipc: mroute: inbound vethHR is not a known phyint

Works for me, I use veth pairs in the SMCRoute test suite. Maybe you could share with us how you set it all up? I assume you've set IP addresses on all interfaces correctly?
