Hi All,
I’m having a strange issue with some VyOS boxes which are connected via a /31.
All ping packets between the two routers are duplicated (screenshot: http://i.imgur.com/OHzB2NV.png) and sending a ping from router B to router A requires the “allow-broadcast” addition.
Is this due to a limitation in support for /31 networks in VyOS, or is it a configuration issue? If useful, I can post the configurations for both boxes.
Thanks!
EDIT: Looks like this was an issue with the Hyper-V cluster the boxes were hosted on.
