VPLS Enhancements
Alcatel-Lucent’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 Information Base (FIB) management features on a per service level 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.
• 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.
• IGMP snooping on a per-SAP and per-SDP basis.
• Optional SAP and/or spoke SDP redundancy to protect against node failure.
