Figure 49: Access to the SPBM Core

For Layer 2 virtualized bridging (Layer 2 VSN), identify all the VLANs that you want to migrate into

SPBM and assign them to an I-SID on the BEB.

For Layer 3 virtualized routing (Layer 3 VSN), map IPv4-enabled VLANs to VRFs, create an IP VPN

instance on the VRF, assign an I-SID to the VRF, and then configure the desired IP redistribution of

IP routes into IS-IS.

All BEBs that have the same I-SID configured can participate in the same VSN. That completes the

configuration part of the migration and all the traffic flows return to normal operation.

SPBM on VSP 4000 supports the following traffic:

• Layer 2 bridged traffic (Layer 2 VSN)

• IPv4 unicast routed traffic on the Global Router (IP shortcuts)

• IPv4 unicast routed traffic using a VRF (Layer 3 VSN)

• IPv4 unicast routed traffic using different VSNs, which have different I-SIDs (Inter-VSN)

• Layer 2 IP multicast traffic in a bridged network (Layer 2 VSN with IP multicast over Fabric

Connect)

• IPv4 multicast routed traffic on the Global Router (IP shortcuts with IP multicast over Fabric

Connect)

• IPv4 multicast routed traffic using a VRF (Layer 3 VSN with IP multicast over Fabric Connect)
