Configuring basic SPBM settings on BEBs and BCBs

For SPBM to run, you must configure all settings in this section on all BEBs and BCBs.

Configuring MST region parameters

CAUTION:
Changing MST region settings causes spanning tree recalculation. Make sure you understand the impact
on your network before you activate the MST region settings.
SPBM runs on MSTI 4092. For two SPBM neighbors to establish an adjacency, you must activate MSTI
4092 on both neighbors and make sure their in-between link has connectivity. To forward traffic on the
link, you must also configure the same MST region parameters on the devices, including:
Format selector. The value for this parameter is fixed at 0.
•
• Region name.
Revision level.
•
VLAN-to-MSTI mapping table.

Configuring the AP mode
Remarks
IMPORTANT:
To ensure correct path selection and traffic
forwarding, make sure B-VLAN to ECT algorithm
mappings and ISIS-SPB timer settings are
consistent across the network.
By default, all B-VLANs are mapped to ECT
algorithm 1.
To optimize traffic distribution, map B-VLANs to
different ECT algorithms.
To obtain a desirable path, you could change
the bridge priority and link metric values.
The following features help you manage the
network:
•
Dynamic hostname exchange—Enables you
to identify SPBM nodes with symbolic
hostnames.
•
Adjacency change logging—Enables you to
track all adjacency changes. To suppress
frequent adjacency change messages,
disable this function.
•
SNMP notifications for SPBM—Enables you
to send SPBM event notifications to an NMS.
Perform this task to prevent temporary loops that
might occur when the topologies of SPBM
neighbors do not match.
