Hi all,
I'm at customer site to configure an m8000 with 9 zones and Solaris 10 U7 fresh installation with the latest kernel patch (141414-10) The domain uses only 2 nics (bge0 and nxge0) configured in C class with vlan tagging and ipmp active-active:


bge15000 + nxge15000 ==> ipmp15 with defrouter 10.1.115.254
bge16000 + nxge16000 ==> ipmp16 with defrouter 10.1.116.254
bge17000 + nxge17000 ==> ipmp17 with defrouter 10.1.117.254
bge18000 + nxge18000 ==> ipmp18 with defrouter 10.1.118.254

GZ          ==> ipmp15
NGZ 1 to 3  ==> ipmp18
NGZ 4 to 6  ==> ipmp38
NGZ 7 to 9  ==> ipmp39

How can we see the configuration above need 4 defrouters, one for the GZ and three for the NGZ
Here's the output of 'netstat -rn' after the boot of all zones:

Routing Table: IPv4
Destination Gateway Flags Ref Use Interface -------------------- -------------------- ----- ----- ---------- ---------
default              10.1.115.254         UG        1          0
default 10.1.116.254 UG 1 1 bge16000 default 10.1.117.254 UG 1 2 bge17000 default 10.1.118.254 UG 1 2 bge18000 139.164.63.0 10.1.115.25 U 1 1 bge15000 224.0.0.0 10.1.115.25 U 1 0 bge15000
127.0.0.1            127.0.0.1            UH        1         42 lo0


The steps above configure perfectly all the 9 NGZ and they run well.
The problem is on the Global Zone:
the clients that use GZ to manage the system get diconnected regularly or sometimes can't connect! When that happens, trying traceroute to clients from GZ console seems that it uses a bad defrouter, the one on another vlan, not the right one!!! (for example 10.1.117.254 on bge17000 insted of 10.1.115.254 on bge15000)

I didn't find a way to make it run correctly.

I've tryied to set a fixed route in GZ to the clients network and it seems to go... but in this way the NGZ can't reach clients because they use the wrong default router to contact the right network.

I've followed all the procedures and the best practices...

Any idea how to configure defrouter in GZ and to make it run?

Best regards,
Stefano
