--s/l3CgOIzMHHjg/5 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable It appears the MONITOR flag doesn't work on gre interfaces. I have a GRE tunnel set up between a FreeBSD 8.2-RELEASE box and a Juniper router. Config on the FreeBSD end: gre0: flags=3D4b051<UP,POINTOPOINT,RUNNING,LINK0,LINK1,MULTICAST,MONITOR> m= etric 0 mtu 1476 tunnel inet 10.162.163.133 --> 10.162.163.131 inet6 fe80::20c:29ff:fe9f:de64%gre0 prefixlen 64 scopeid 0x6 inet 10.200.0.2 --> 10.200.0.1 netmask 0xfffffffc nd6 options=3D3<PERFORMNUD,ACCEPT_RTADV> Config on the Juniper end: tunnel { source 10.162.163.131; destination 10.162.163.133; } family inet { address 10.200.0.1/30; } And from the Juniper, I am able to ping the 10.200.0.2 IP on the FreeBSD end of the GRE tunnel. As I understand it, this shouldn't happen with the MONITOR flag there, right? > ping 10.200.0.2 rapid PING 10.200.0.2 (10.200.0.2): 56 data bytes !!!!! --- 10.200.0.2 ping statistics --- 5 packets transmitted, 5 packets received, 0% packet loss round-trip min/avg/max/stddev =3D 0.265/0.297/0.382/0.043 ms --=20 Chip Marshall <chip@2bithacker.net> http://2bithacker.net/ --s/l3CgOIzMHHjg/5 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (Darwin) iEYEARECAAYFAlGKdUYACgkQnTUxIUPEgZ4QVQCeKmEMa2iS51nXkp52PARuiCtq SJUAn0dpF6yVrTSh+dJd6oAtO8ulgT+O =3HX7 -----END PGP SIGNATURE----- --s/l3CgOIzMHHjg/5--
