Multihome routing at 8132F

Hello,

I would like to know did 8132F support multihome routing?

I have enabled 'IP routing' at switch already.  There are two subnet for inter routing active now.

Example
Subnet A: 111.222.333.0/24

Subnet B: 555.666.777.0/24

The switch itself default route is 111.222.333.1/24 to Internet

All traffic must via the Switch to allow routing between them those two subnet at above.

However, Subnet B could not allow via Switch's default gateway and require to routing thru another gateway 555.666.777.1/24

How should I config it to support multi-home routing?

Thanks in advance.
