Stateless redundancy does not have information about MSAP because MCS is not used for synchronizing subscriber host information.
Static SAPs must be configured to rewrite FDBs on Layer 2 switches with G-ARP in access or aggregation networks.
Use the following CLI commands to rewrite FDBs with G-ARP.
group-interface <ip-int-name>
sap <sap-id> create
no shutdown
This requires the aggregation network to re-learn MAC for multiple C-VLANs using a single G-ARP from a specific C-VLAN.
Two typical scenarios are supported:
MSAP has qinq encap, and aggregation switches have per SVLAN FDB
MSAP has dot1q encap, and aggregation switches have per SVLAN FDB
(Aggregation switches push SVID)
