Solaris + Switches + VLANs = wtf?

Hey guys!

I am attempting to put a solaris box that is currently on 2 subnets using
two interfaces and one switch onto a third subnet using a second switch and
a second nic. However, I cannot for the life of me bring it online in the
third subnet.

i have the first nic (two interfaces: e1000g0 and e1000g1) online in two
subnets; 192.168.XX5.13 and 192.168.XX6.13, netmask 255.255.255.0. This is
plugged into an HP switch with the appropriate vlans assigned to the ports
on the switch where the ethernet is plugged in.

i have the second nic (bnx0) plugged into the second switch, the appropriate
vlan set, and the ip statically set to 172.XX.237.21 with a netmask of
255.255.254.0

Here is the routing table from another box with a similar arrangement that
works that i would like to emulate:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
192.168.X15.0   *               255.255.255.0   U     0      0        0 eth0
172.XX.236.0    *               255.255.254.0   U     0      0        0 eth1
172.XX.0.0      172.XX.236.1    255.255.0.0     UG    0      0        0 eth1
169.254.0.0     *               255.255.0.0     U     0      0        0 eth1
default         woot.local 0.0.0.0         UG    0      0        0 eth0

Here is the routing table from the solaris box i am having trouble with:

IRE Table: IPv4

0   5 UH     118      0

Any networking gurus that can weigh in on this one? Please?
