ECMP load sharing for IPv6
Disabling or re-enabling ECMP load sharing for IPv6
ECMP load sharing for IPv6 is enabled by default. To disable the feature, enter the following
command.
Brocade(config)#no ipv6 load-sharing
If you want to re-enable the feature after disabling it, you must specify the number of load-sharing
paths. The maximum number of paths the device supports is a value from 2–8. By entering a
command such as the following, iPv6 load-sharing will be re-enabled.
Brocade(config)#ipv6 load-sharing 4
Syntax: [no] ipv6 load-sharing num
The num parameter specifies the number of paths and can be from 2-8. The default is 4.
Changing the maximum load sharing paths for IPv6
By default, IPv6 ECMP load sharing allows traffic to be balanced across up to four equal paths. You
can change the maximum number of paths the device supports to a value from 2-8.
To change the number of ECMP load sharing paths for IPv6, enter a command such as the
following.
Brocade(config)#ipv6 load-sharing 6
Syntax: [no] ipv6 load-sharing [num]
The num parameter specifies the number of paths and can be from 2-8. The default is 4.
Enabling support for network-based ECMP
load sharing for IPv6
Network-based ECMP load sharing is supported. In this configuration, traffic is distributed across
equal-cost paths based on the destination network address. Routes to each network are stored in
CAM and accessed when a path to a network is required. Because multiple hosts are likely to
reside on a network, this method uses fewer CAM entries.
Displaying ECMP load-sharing information for IPv6
To display the status of ECMP load sharing for IPv6, enter the following command.
Brocade#show ipv6
