Never mind the above. I just tested it myself and indeed both
addresses are listed by "ip addr" and "show interfaces".

I did the same on FreeBSD and "show interfaces" correctly returns
only the tunnel IP address, so it seems there is a Linux-specific
bug in the FEA the way it handles the p2p IP addresses.

Please try the above as a short-term solution while I fix the Linux
GRE issue.
