    Greetings.

    I've had some success setting up double tagging on an ip interface and setting up BGP. I configured a virtual ip on that same interface but it looks like traffic is not egressing the interface at all when pinging the remote end of the secondary /30. tcpdump doesn't show anything exiting the interface whilst a ping is running.

    I tested with a single tagged interface and virtual ip, like the two /30s above, and it works.

    Is setting up a virtual ip on a double tagged interface supported, or supposed to work at all?

    Thanks.

      Did a bit more testing. Setup facing switch (qfx5100) to push/pop the stag so I could setup only one tag since it' worked on another interface. Unfortunately it doesn't work in this scenario either. The difference here is I see arp requests from pfsense on a tcpdump of the interface, nothing comes back from the far end. Primary interface ip works fine and BGP is up.

      Unsure of what to test next.
