Configuring IPv6 FIB-Based Forwarding

With the IPv6 FIB caching function enabled, the device searches the FIB cache to forward packets, thus

reducing the searching time and improving forwarding efficiency.
In the IPv6 FIB load sharing mode, the device can decide how to select equal cost multi-paths (ECMP) to
forward packets. Currently, two load sharing modes are supported:

Load sharing based on the HASH algorithm: A certain algorithm based on the source IPv6 address
and destination IPv6 address is adopted to select an ECMP route to forward packets.

Load sharing based on polling: Each ECMP route is used in turn to forward packets.

Follow these steps to configure the IPv6 FIB-based forwarding:

To do…

Use the command…

By default, the load sharing based

on polling is adopted, or in other

words, each ECMP route is used in
turn to forward packets.
