I'm trying to setup multiple layers of IPIP tunnels on a FreeBSD system
(destined to Cisco routers). I have what I believe is the correct setup
on the FreeBSD box but am getting a ping error when testing the second
IPIP tunnel:
bash-2.05b# ping 10.2.2.2
PING 10.2.2.2 (10.2.2.2): 56 data bytes
ping: sendto: Input/output error
ping: sendto: Input/output error
ping: sendto: Input/output error
The first tunnel works fine and if I generate the ping from the Cisco side
(on the second tunnel) the packets get to the FreeBSD box just fine.
Here's my interface config:
bash-2.05b# gifconfig -a
gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
inet 10.1.1.1 --> 10.1.1.2 netmask 0xfffffffc
inet6 fe80::2e0:81ff:fe24:eff4%gif0 prefixlen 64
physical address inet xxx.xxx.xxx.125 --> xxx.xxx.xxx.234
gif1: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
inet 10.2.2.1 --> 10.2.2.2 netmask 0xfffffffc
inet6 fe80::2e0:81ff:fe24:eff4%gif1 prefixlen 64
physical address inet 10.1.1.1 --> 10.1.1.2
Can anyone tell me what I've got setup wrong here or at the least what the
'Input/output error' indicates?
