Mulitple Zones on Dual NIC host
Greetings Forumers!

I am running into an issue with multiple zones on an M5000 with 2 NICs. The NICs are on separate VLANs. These zones are using the 2 NICs to communicate with other systems but when they need to communicate with a zone on the same system, but different NIC, the application fails. The network guys here indicate that no packets leave the origination NIC. And, when I run a traceroute from one zone (on NIC#1) to another zone (on NIC#2), the traceroute take 1 hop but never access the default gateway.

Here's some diag:
Code:
root@globalzone# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000

Notice the packets don't go through the default gateway.

This is a problem because the application on zone1 will not start due to a communication issue.

I'm trying to get the zone to send the packets to the default g/w so the app comes up.


Any assistance is greatly appreciated in advance!
