configuration of external bridge network

Hi, all.

I'm trying to configure external bridge network using examples from MPSS_Users_Guide.

I want to access host CPU and MIC from other PCs at the same subnet network.

Then, I wrote ifcfg-br0 file as follows

DEVICE=br0
BOOTPROTO=none
ONBOOT=yes
IPADDR=<IP_A>
NETMASK=255.255.255.0
TYPE=Bridge
MTF=9000

and executed following commands

micctrl --addbridge=br0 --type=external --ip=<IP_A> --netbits=16 mic0
micctrl --network=static --bridge=br0 --ip=<IP_B>

(micctrl --network=static --bridge=br0 --ip=<IP_B> --netbits=16 mic0 cause warning and the same incorrect result is obtained)

After that, network and mpss services are restarted.

Then, IP address of each network interfaces are as follows

# ifconfig | grep -e "Link " -e "inet "
br0       Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
          inet addr:<IP_A>  Bcast:<IP_A_Bcast>  Mask:255.255.255.0
eth0      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
          inet addr:<IP_C>  Bcast:<IP_A_Ccast>  Mask:255.255.0.0
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
mic0      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx

As a result, I confirmed that I can login to CPU and MIC by ssh from host CPU.

However, from other PCs, I can login to CPU but I can't login to MIC.

Would you show me the correct procedures of network configuration ?

Kind regards
