The internal LPM tables are provided on all platforms.
The ExtremeXOS software manages the content of the hardware tables based on the configuration specified by the following commands:
configure iproute reserved-entries [num_routes_needed|maximum|default] slot [all|slot_num]
The configure iproute reserved-entries command configures the LPM tables.
The configure forwarding internal-tables [ l2-and-l3 | more [l2 | l3-and-ipmc | routes] ] command provides the ability to support additional IPv4 and IPv6 hosts and multicast table entries on all Summit and ExtremeSwitching platforms.
IPv6 hardware and slowpath forwarding are supported on user-created Virtual Routers, and IPv6 tunnels are only supported on VR-Default.
The size of the internal LPM tables, and the size of the L3 Hash and Next Hop tables are fixed for some platforms. The following tables list the hardware capacity for each of the tables shown in Hardware Forwarding Tables.
Summit X670-G2 and X770 series switches have hardware forwarding tables internal to the switch chips that can be partitioned in a flexible manner. The Summit X670-G2 and X770 switches have the following configurable internal tables.
