Procedure

Create an Alieas for ETH1

On VICTORIA, run the following commands to create a subinterface on eth1:

cat >ifcfg-eth1:1 <<DONE

# Intel Corporation 82571EB Gigabit Ethernet Controller

DEVICE=eth1:1

HWADDR=00:1B:21:D9:A1:AF

ONBOOT=yes

BRIDGE=xenbr1

NM_CONTROLLED=no

DONE

Create the Bridge for the RAC Interconnect

On VICTORIA, run the following commands to create a brigdeg that uses a subinterface on eth1:

cd /etc/sysconfig/network-scripts

cat >ifcfg-xenbr1 <<DONE

DEVICE=xenbr1

TYPE=Bridge

BOOTPROTO=static

BROADCAST=192.168.2.255

IPADDR=192.168.2.1

NETMASK=255.255.255.0

ONBOOT=yes

DELAY=0

NM_CONTROLLED=no

DONE

Activate the Bridge

The new bridge is activated by restarting the network service as follows:

service network restart
