The Nokia VPLS implementation includes several enhancements beyond basic VPN connectivity. The following VPLS features can be configured individually for each VPLS service instance:
Extensive MAC and IP filter support (up to Layer 4). Filters can be applied on a per SAP basis.
Forwarding Information Base (FIB) management features including:
Configurable FIB size limit
FIB size alarms
MAC learning disable
Discard unknown
Separate aging timers for locally and remotely learned MAC addresses.
Ingress rate limiting for broadcast, multicast, and destination unknown flooding on a per SAP basis.
Implementation of Spanning Tree Protocol (STP) parameters on a per VPLS, per SAP and per spoke-SDP basis.
Optional SAP and spoke-SDP redundancy to protect against node failure.
IGMP snooping on a per-SAP and SDP basis.
