Step 13 instance id
Example:
RP/0/RSP0/CPU0:router(config-mstag-if)# instance 1
Enters the MSTI configuration submode.
Allowed values for the MSTI ID are from 0 through 4094.
Step 14 edge mode
Example:
RP/0/RSP0/CPU0:router(config-mstag-if-inst)# edge mode
Enables access gateway edge mode for this MSTI.
Step 15 vlan-id vlan-range [, vlan-range ] [,vlan-range ] [,vlan-range ]
Example:
RP/0/RSP0/CPU0:router(config-mstag-if-inst)# vlan-id 2-1005

List of VLAN ranges in the form a-b, c, d, e-f, g, and so on.
Step 16 priority priority
Example:
RP/0/RSP0/CPU0:router(config-mstag-if-inst)# priority 4096
Sets the bridge priority for the current MSTI.
Allowed values are from 0 through 61440 in multiples of 4096.
Step 17 port-priority priority
Example:
RP/0/RSP0/CPU0:router(config-mstag-if-inst)# port-priority 160
Sets the port priority performance parameter for the MSTI.
Allowed values for port priority are from 0 through 240 in multiples of 16.
Step 18 cost cost
Example:
RP/0/RSP0/CPU0:router(config-mstag-if-inst)# cost 10000
