Yes, this is a bug, and your solution appears correct.
Applied in CVS:
xorp/fea/data_plane/ifconfig/ifconfig_parse_netlink_socket.cc
rev. 1.16

BTW, what program and command did you use to create the p2p tunnel
and to trigger the problem? This piece of information could be
useful for future testing of the p2p cases.

Thanks,
Pavlin
