Feature Restrictions and guidelines
VLAN
Do not use B-VLANs for other purposes such as EVI extended VLANs or VLAN
interfaces. Before specifying a VLAN as a B-VLAN, you must remove all features
that have been configured on the VLAN.
You must configure the provider network ports on BEBs and BCBs as trunk or
hybrid ports, and assign them to all B-VLANs as tagged VLAN members.
ISIS-SPB protocol frames are transmitted untagged on links. To prevent these
frames from being dropped, assign each SPBM-enabled interface to the port
VLAN (PVID). If the link type is hybrid, specify the interface as an untagged
member of the port VLAN.
Licensing requirements
SPBM requires a license. For information about feature licensing, see Fundamentals Configuration
Guide.
SPBM configuration task list
Tasks at a glance Remarks
(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
• Configuring the SPBM multicast replication mode on
BEBs
Configure customer-side settings to map Ethernet
service instances to SPB VSIs for extending
C-VLANs across different sites.
Each Ethernet service instance represents a set of
C-VLANs.
Make sure the multicast replication mode for an
SPB VSI is the same across all BEBs.
(Optional.) Enabling the multicast B-VLAN feature
Perform this task if tandem multicast replication is
used.
