2. Usage:
Use this command to specify the maximum allowed hops for BPDU in an MST region. This parameter is used by all the instances
of the MST. Specifying the max hops for a BPDU prevents the messages from looping indefinetely in the network. When a bridge
receives a MST BPDU that has exceeded the allowed max-hops, it discards the BPDU.
3. Command Syntax:
bridge GROUP max-hops HOP_COUNT
no bridge GROUP max-hops
GROUP <1-1> Specify the bridge-group ID.
HOP_COUNT Maximum hops the BPDU will be valid for.
4. Example:
The following example specifies the maximum allowed hops (25) for BPDU in bridge GROUP (1):
switch_a(config)#bridge 1 max-hops 25
switch_a(config)#
