Cisco ASR 9000 Series Configuration Guidelines

Step 6 root-priority priority
Example:
RP/0/RSP0/CPU0:router(config-pvstag-if-vlan)# root-priority 4096
Sets the root bridge priority for the BPDUs sent from this port.
Step 7 root-id id
Example:
RP/0/RSP0/CPU0:router(config-pvstag-if-vlan)# root-id 0000.0000.0000
Sets the identifier of the root bridge for BPDUs sent from a port.
Step 8 root-cost cost
Example:
RP/0/RSP0/CPU0:router(config-pvstag-if-vlan)# root-cost 10000
Set the root path cost to sent in BPDUs from this interface.
Step 9 priority priority
Example:
RP/0/RSP0/CPU0:router(config-pvstag-if-vlan)# priority 4096
Sets the bridge priority for the current MSTI.
For PVSTAG, allowed values are from are 0 through 65535; for PVRSTAG, the allowed values are from 0 through
61440 in multiples of 4096.
Step 10 bridge-id id
Example:
RP/0/RSP0/CPU0:router(config-pvstag-if-vlan)# bridge-id 001c.0000.0011
Sets the bridge ID for the current switch.
Step 11 port-priority priority
Example:
RP/0/RSP0/CPU0:router(config-pvstag-if-vlan)# port-priority 160
Sets the port priority performance parameter for the MSTI.
For PVSTAG, allowed values for port priority are from 0 through 255; for PVRSTAG, the allowed values are from 0
through 240 in multiples of 16.
Step 12 port-id id
