Hi,

If I configure a gre tunnel, between two end-points, I'm able to view the
point-to-point IP addresses of the tunnel using ifconfig, e.g.:

gre1: flags=b051<UP,POINTOPOINT,RUNNING,LINK0,LINK1,MULTICAST> mtu 1476
        inet6 fe80::2a0:c9ff:fea3:4b75%gre1 prefixlen 64 scopeid 0x5
        inet 192.168.254.2 --> 192.168.254.1 netmask 0xffffff00

Unfortunately, I cannot find a way to show which physical IP addresses I
have configured for the tunnel (i.e. the addresses configured with ifconfig
gre1 tunnel src dst). 

Doe anyone know a command to show these (other than tcpdump :-)?

If it matters, this particular system is using FreeBSD 5.0 RELEASE.

Kind regards,

                  Frank
