No IP Routing Mode
The no IP routing mode bridges all packets, both IP and non-IP, and prevents routing. Although Cisco
IOS can use the IP addresses for interfaces configured as management ports, it will not route between
these IP addresses.
The global command no ip routing enables this feature, and enabling no ip routing disables the other
modes.
The following rules help describe packet handling in this mode:

6-6
All the interfaces and subinterface belonging to the same bridge-group need consistent configuration
with regard to IP addresses. Either all of the bridge group's interfaces should be configured with IP
addresses or none of the bridge group's interfaces should be configured with IP addresses.
shows ML-Series card interfaces configured in a bridge group with no IP addresses.
Bridge Group with No IP Address
shows ML-Series card interfaces configured with IP addresses but not in a bridge group.
IP Addresses with No Bridge Group
shows ML-Series card interfaces configured with IP addresses and in a bridge group.
IP Addresses with Bridge Group
An input interface or subinterface configured with only a bridge-group and no ip addresses bridges
all packets (Example 6-7).
