SPBM configuration task list

(Required.) Configuring basic SPBM settings on BEBs and BCBs:

• Configuring MST region parameters

• Enabling SPBM

You must map B-VLANs to MSTI 4092, and enable SPBM both globally and on the provider network ports in the SPBM network.

(Required.) Configuring customer-side settings on BEBs:

• Enabling L2VPN

• Creating an SPB VSI

• Assigning a B-VLAN to an SPB VSI

• Configuring Ethernet service instances on BEBs

Configure customer-side settings to map Ethernet service instances to SPB VSIs for extending VLANs across different sites.

Each Ethernet service instance represents a set of VLANs.

Configuring SPBM multicast settings:

• (Required.) Configuring the SPBM multicast replication mode on BEBs

• (Optional.) Setting the SPSource ID

Make sure the multicast replication mode for an SPB VSI is the same across all BEBs.

(Optional.) Optimizing traffic distribution:

• Setting the bridge priority

• Setting a link metric value for a provider network port

• Mapping B-VLANs to an ECT algorithm

• Performing ECT migration for an SPB VSI

To obtain a desirable path, you can change the bridge priority and link metric values.

By default, all B-VLANs are mapped to ECT algorithm 1. To optimize traffic distribution, map B-VLANs to different ECT algorithms.

(Optional.) Configuring the AP mode

Perform this task to prevent temporary loops that might occur when the topologies of SPBM neighbors do not match.

(Optional.) Optimizing the SPBM network:

• Enabling dynamic hostname exchange

• Configuring ISIS-SPB throttling timers:

  • Tuning ISIS-SPB adjacency maintenance settings

  • Tuning ISIS-SPB LSP timers

  • Tuning the SPF calculation timer

  • Setting the LSDB overload bit

• Configuring the control MAC address for ISIS-SPB

	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.

Dynamic hostname exchange enables you to identify SPBM nodes with symbolic hostnames.

(Optional.) Configuring ISIS-SPB authentication:

• Configuring ISIS-SPB adjacency authentication

• Configuring ISIS-SPB area authentication

Configure ISIS-SPB authentication to improve security in an SPBM network.

(Optional.) Configuring Graceful Restart for ISIS-SPB

Enable this feature before you re-enable SPBM or perform an active/standby switchover. Graceful Restart ensures nonstop forwarding while ISIS-SPB processes are re-establishing their adjacency.

(Optional.) Enabling NSR for ISIS-SPB

NSR ensures nonstop services when ISIS-SPB has redundant processes on multiple IRF member devices.

(Optional.) Configuring SNMP notifications and context for SPBM

Configure SNMP notifications for SPBM to send SPBM event notifications to an NMS.

(Optional.) Enabling ISIS-SPB adjacency change logging

Enable this feature to track all adjacency changes. To suppress frequent adjacency change messages, disable this feature.
