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/or spoke-SDP redundancy to protect against node failure
IGMP snooping on a per-SAP and SDP basis
