[CentOS] 2 or more bridges not working

Hi,


Adding one bridge to cent7 works fine.  But when adding a 
second bridge it either takes the IP from the First bridge and
stops the first bridge from working or
Stops the first bridge from working and does not work for either
bridge

I’m adding

BRIDGE=br3
to ifcfg-eth0

and then
creat ifcfg-br3
and adding the necessary requirments TYPE, BOOTPROTO,
DELAY

Is there a reason why Cent7 won’t except two or more bridges?

I’m using NM after a yum update.

Best,


Steve
