Hello all,

I would like to use two network interfaces.
It is working but I notice that both bridges hace the same id.

#brctl show
bridge name     bridge id               STP enabled     interfaces
xenbr0          8000.feffffffffff       no        peth0
                                                        vif0.0
                                                        vif10.0
xenbr1          8000.feffffffffff       no        peth1
                                                        vif0.1
                                                        vif10.1

Is that normal?
Could it possibly cause network performance loss?

I am using this script to set them up.

/etc/xen/scripts/my-network-bridge
#!/bin/bash

case "$1" in
start)
/etc/xen/scripts/network-bridge start bridge=xenbr0 netdev=eth0
vifnum=0 antispoof=no
/etc/xen/scripts/network-bridge start bridge=xenbr1 netdev=eth1
vifnum=1 antispoof=no
;;
stop)
/etc/xen/scripts/network-bridge stop bridge=xenbr0 netdev=eth0 vifnum=0
/etc/xen/scripts/network-bridge stop bridge=xenbr1 netdev=eth1 vifnum=1
;;
restart)
$0 stop
$0 start
;;
*)
echo "usage: $0 {start|stop|restart}"
esac
exit 0


Thanks.
Chris.
