Network Bridge – Bring Down and Delete Bridge Interface

bridgenetworking

How do I remove a bridge that has an IP address that was brought up manually and isn't in /etc/network/interfaces?

$ ifconfig br100                                                
    br100     Link encap:Ethernet  HWaddr 00:00:00:00:00:00                         
              inet addr:172.16.0.5  Bcast:172.16.0.255  Mask:255.255.255.0

Can't delete it:

# brctl delbr br100
bridge br100 is still up; can't delete it

Can't bring it down with ifdown:

# ifdown br100                                                  
ifdown: interface br100 not configured

Figured it out:

# ip link set br100 down
# brctl delbr br100
