  • UNIFIED FORWARDING TABLE

    • Flexibly allocate L2 MAC, L3 host and LPM (Longest

    Prefix Match) resources from a single pool • L3 host holds /32 IPv4 or /128 IPv6 routes

    • LPM table holds any routes not handled by L3 host table

    • Optimized forwarding table size based on deployment

    scenarios
