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...
Enter system view

If too many ICMPv6 error packets are sent within a short time in a network,
network congestion may occur. To avoid network congestion, you can control the
maximum number of ICMPv6 error packets sent within a specified time, currently
by adopting the token bucket algorithm.
You can set the capacity of a token bucket, namely, the number of tokens in the
bucket. In addition, you can set the update period of the token bucket, namely,
the interval for updating the number of tokens in the token bucket to the
configured capacity. One token allows one ICMPv6 error packet to be sent. Each
time an ICMPv6 error packet is sent, the number of tokens in a token bucket
decreases by one. If the number of ICMPv6 error packets successively sent exceeds
the capacity of the token bucket, subsequent ICMPv6 error packets cannot be sent
out until the number of tokens in the token bucket is updated and new tokens are
added to the bucket.
Follow these steps to configure the capacity and update period of the token
bucket:
To do...
Enter system view

-
Required
Disabled by default
Optional
By default, the load sharing
based on polling is
adopted, that is, each
ECMP route is used in turn
to forward packets.
