Nokia's 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 Database (FDB) management features on a per service-level basis including:
Configurable FDB size limit. On the 7450 ESS, it can be configured on a per-VPLS, per-SAP, and per spoke-SDP basis.
FDB size alarms. On the 7450 ESS, it can be configured on a per-VPLS basis.
MAC learning disable. On the 7450 ESS, it can be configured on a per-VPLS, per-SAP, and per spoke-SDP basis.
Discard unknown. On the 7450 ESS, it can be configured on a per-VPLS basis.
Separate aging timers for locally and remotely learned MAC addresses.
Ingress rate limiting for broadcast, multicast, and unknown destination flooding on a per-SAP basis.
Implementation of STP parameters on a per-VPLS, per-SAP, and per spoke-SDP basis.
A split horizon group on a per-SAP and per spoke-SDP basis.
DHCP snooping and anti-spoofing on a per-SAP and per-SDP basis for the 7450 ESS or 7750 SR.
IGMP snooping on a per-SAP and per-SDP basis.
Optional SAP and, or spoke-SDP redundancy to protect against node failure.
