	Thanks to all for your help,

 shame on me, it was a faulty routerconfiguration, the configuration on the
sun was ok. I was only looking at the wrong place as was suggested by Caspar

>They are send to the ethernet address of the router; the fact that

Betreff: defaultroute not working

Hi all,

 I have some silly problem here that is driving me nuts. On my
Blade100/Solaris9 the defaultroute is not used.
The local network is fine, everything ist reachable but when I try to reach
a maschine not on my network, instead of sending the data to the default
router my Blade is trying to connect the target maschine directly, even if
the default route is defined. The defaultrouter is reachable if I ping it.
What is wrong here ?

here's the configuration:

root@spica [7] 67 /etc> ifconfig -a
--- snip ---
eri0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet netmask ffff0000 broadcast
        ether 0:3:ba:4:b1:af

root@spica [7] 68 /etc> cat defaultrouter

root@spica [7] 69 /etc> netstat -r

Routing Table: IPv4
  Destination           Gateway           Flags  Ref   Use   Interface
-------------------- -------------------- ----- ----- ------ ---------                 U         1     28  eri0
BASE-ADDRESS.MCAST.NET spica                U         1      0  eri0
default               UG        1      3
localhost            localhost            UH       63   5867  lo0

Pinging the local net works fine

ping is alive

root@spica [5] 49 /etc> snoop icmp
Using device /dev/eri (promiscuous mode)
       spica ->   ICMP Echo request (ID: 2524 Sequence
number: 0) -> spica        ICMP Echo reply (ID: 2524 Sequence number:

Pinging the remote net the defaultrouter is ignored

root@spica [7] 75 /etc> ping

root@spica [5] 51 /etc> snoop icmp
Using device /dev/eri (promiscuous mode)
       spica -> ICMP Echo request (ID: 2527 Sequence number: 0)
       spica -> ICMP Echo request (ID: 2527 Sequence number: 1)
