Repeat steps 11 to 13 for each MSTI.
Note
Step 14 interface { Bundle-Ether | GigabitEthernet | TenGigE | FastEthernet } instance
Example:
RP/0/RSP0/CPU0:router(config-mstp)# interface FastEthernet 0/0/0/1
RP/0/RSP0/CPU0:router(config-mstp-if)#
Enters the MSTP interface configuration submode, and enables STP for the specified port.
Forward interface in Rack/Slot/Instance/Port format.
Step 15 instance id port-priority priority
Example:
RP/0/RSP0/CPU0:router(config-mstp-if)# instance 101 port-priority 160
Sets the port priority performance parameter for the MSTI.
Allowed values for the MSTI ID are from 0 through 4094.
Allowed values for port priority are from 0 through 240 in multiples of 16.
Step 16 instance id cost cost
Example:
RP/0/RSP0/CPU0:router(config-mstp-if)# instance 101 cost 10000
Sets the internal path cost for a given instance on the current port.
Allowed values for the MSTI ID are from 0 through 4094.
Allowed values for port cost are from 1 through 200000000.
Repeat steps 15 and 16 for each MSTI for each interface.
Step 17 external-cost cost
Example:
RP/0/RSP0/CPU0:router(config-mstp-if)# external-cost 10000
Sets the external path cost on the current port.
Allowed values for port cost are from 1 through 200000000.
Step 18 link-type { point-to-point | multipoint }
Example:
RP/0/RSP0/CPU0:router(config-mstp-if)# link-type point-to-point
Sets the link type of the port to point-to-point or multipoint.
