Hello all

I'm trying to configure a v120 (sol8) as router. The exact setup is:

2900 switch
|
|
eri0 eri1 (node1 v120 sol8)----------------------> eri0 (node2 v120 sol8)



so node1 eri1 is connected to node2 eri0.
Also, on node1 i did: ndd -set /dev/ip ip_forwarding 1

from node 1: I can ping eri0 on node2 & 2900
from node2: I can ping eri0 + eri1 on node1.

problem: from node2 I can not reach the switch.

node2 ifconfig:

bash-2.03# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
eri0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 192.168.10.10 netmask ffffff00 broadcast 192.168.10.255
ether 0:3:ba:b:df:a3
eri1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
inet 10.1.1.10 netmask ff000000 broadcast 10.255.255.255
ether 0:3:ba:b:df:a4

Routing table node2:

bash-2.03# netstat -rn

Routing Table: IPv4
Destination Gateway Flags Ref Use Interface
-------------------- -------------------- ----- ----- ------ ---------
192.168.10.0 192.168.10.10 U 1 0 eri0
10.0.0.0 10.1.1.10 U 1 0 eri1
224.0.0.0 127.0.0.1 U 1 0 lo0
default 192.168.10.30 UG 1 0
127.0.0.1 127.0.0.1 UH 5 60 lo0



When I ping the switch from node2 & run a snoop on node1:

Using device /dev/eri (promiscuous mode)
node1 -> (broadcast) ARP C Who is 192.168.10.30, 192.168.10.30 ?

node1 gateways:
bash-2.03# cat gateways
net 10.0.0.0 gateway 10.1.1.2 metric 1 passive


The problem is that once the ping response reaches node1 it's not able to route it accordingly. I don't see how since the routing table clearly shows an entry.

This has been a nightmare to work out, any help would be appreciated.

Cheers!

hi,

not quite clear which net goes to which intf, where to route
but have you route node2 to 2900 via eri1 on node1?
because - it will exactly be the same thing if you ping node2 from 2900.

cheers.
