Introduction

This document provides examples for configuring SPBM.

Prerequisites

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of SPBM.

General restrictions and guidelines

When you use SPBM in conjunction with other features, follow the restrictions and guidelines in Table 1.

Table 1 SPBM and other features compatibility

Feature	Restrictions and guidelines
IRF	You must execute the irf mac-address persistent always command to prevent the IRF bridge MAC address from changing after the address owner leaves the IRF fabric.
Spanning tree	The spanning tree mode must be set to MSTP (the default). For SPBM neighbors to establish adjacencies, you must map all B-VLANs to MSTI 4092 and make sure their in-between links have connectivity. To forward traffic on an SPBM network, you must assign all SPBM nodes to one MST region. For more information about MST region configuration, see Layer 2—LAN Switching Configuration Guide.
Static MAC	If a B-MAC is the same as a static MAC in the MAC address table, remove the static MAC. The device can forward SPBM packets to the B-MAC only after the conflict is removed.
VLAN	ISIS-SPB protocol frames are transmitted untagged on links. To prevent SPBM-enabled interfaces from dropping these frames, assign each SPBM-enabled interface to the port VLAN (PVID) as an untagged member. You must configure the provider network ports on BEBs and BCBs as trunk or hybrid ports, and assign the ports to all B-VLANs as tagged VLAN members.

 

Example: Configuring SPBM with tandem replication

Network configuration

As shown in Figure 1, deploy an SPBM network to meet the following requirements:

·     Use I-SID 3001 to extend VLAN 100 across customer sites 1, 2, 3, and 4.

·     Assign B-VLAN 3001 to I-SID 3001.

·     Use tandem replication for multicast in the SPBM network.

Figure 1 Network diagram

 

	NOTE: BCB 2 uses the same port numbering scheme as BCB 1. BEB 2, BEB 3, and BEB 4 use the same port numbering scheme as BEB 1.

 

Restrictions and guidelines

When you configure SPBM, follow these restrictions and guidelines:

·     The following MST region parameters must be the same across all SPBM nodes:

¡     Region name.

¡     Revision level.

¡     All B-VLANs mapped to MSTI 4092.

·     Multicast replication mode must be the same across all BEBs.

Software versions used

Example: Performing SPBM ECT migration by changing the B-VLAN

Network configuration

As shown in Figure 3, perform ECT migration for the SPBM network (I-SID 3001) in "Example: Configuring SPBM with tandem replication."

Move I-SID 3001 from the original ECT algorithm to ECT algorithm 9. Change the B-VLAN from 3001 to 3003 for I-SID 3001.

Figure 3 Network diagram

 

Analysis

To perform the ECT migration, you must perform the following tasks:

·     Create B-VLAN 3003, and map B-VLAN 3003 to MSTI 4092 on all SPBM nodes.

·     Map B-VLAN 3003 to ECT algorithm 9 on all SPBM nodes.

·     Change the B-VLAN from 3001 to 3003 for I-SID 3001 on BEBs.
