Feature compatibility requirements
When you use SPBM in conjunction with other features, follow the restrictions and guidelines in Table 3.
Table 3: SPBM and other features compatibility
Feature | Restrictions and guidelines |
|---|---|
IRF | You must use the irf mac-address persistent always command to prevent the IRF bridge MAC address from changing after the address owner leaves. For more information about IRF bridge MAC persistence, see IRF Command Reference. |
IS-IS | Provider network ports on BEBs and BCBs cannot be used for setting up standard IS-IS adjacencies. |
Spanning tree | The spanning tree mode must be set to MSTP. 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 the same MST region. For SPBM to run correctly, make sure MSTI 4092 is not used by RRPP or Smart Link. For more information about RRPP and Smart Link, see High Availability Configuration Guide. |
Static MAC | If a B-MAC is the same as a static MAC entry in the MAC address table, remove the static MAC entry. The device can forward SPBM packets to the B-MAC only after the conflict is removed. |
VLAN | Do not use B-VLANs for other purposes such as 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 SPBM-enabled interfaces from dropping these frames, assign each SPBM-enabled interface to the port VLAN (PVID) as an untagged member. Make sure the PVIDs have been created on the device. |
VXLAN | MPLS shares hardware resources with VXLAN on the HPE FlexFabric 5940 switch series. The hardware resources available for MPLS and VXLAN depend on the VXLAN hardware resource mode, which is Layer 2 gateway mode by default. Use this default mode as a best practice to guarantee SPBM sufficient hardware resources. In any other mode than Layer 2 gateway mode, SPBM might not have enough hardware resources. For more information about VXLAN hardware resource modes, see VXLAN Configuration Guide. |
