CAUTION:
To avoid traffic disruption, you must verify that the new mapping has been added across the SPBM
network before you proceed to the next task.
Step Command Remarks
1. Enter SPBM view. spbm
Skip this step if you choose a
VLAN that already exists.
2. Map the new B-VLAN to a new
ECT algorithm.
ect ect-index b-vlan vlan-id-list
This ECT algorithm must be
different from the one mapped
to the old B-VLAN.
3. Verify that the mapping has
been added.
display spbm b-vlan [ vlan-id ] N/A
4. Return to system view. quit N/A
3. Assign the new B-VLAN to the SPB VSI on all BEBs:
Step Command
1. Enter VSI view. vsi vsi-name
2. Enter SPB I-SID view. spb i-sid i-sid
3. Assign the new B-VLAN to the SPB VSI. b-vlan vlan-id
NOTE:
The SPB VSI's traffic will not be switched over to the new path until you assign the new B-VLAN to the
SPB VSI on all BEBs.
Enabling dynamic hostname exchange
ISIS-SPB uses a 6-byte system ID to represent a node in the network. This type of ID is difficult for
administrators to identify devices when they examine ISIS-SPB adjacencies, FDB entries, and LSDB
entries.
Dynamic hostname exchange enables you to assign a symbolic hostname to each SPBM node. ISIS-SPB
advertises this information in the Dynamic hostname TLV in LSPs to remote LSDBs.
To enable dynamic hostname exchange:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter SPBM view. spbm N/A
3. Configure a symbolic
hostname.
is-name is-name
By default, dynamic hostname
exchange is disabled, and no symbolic
hostname is configured for the device.
