ECMP load sharing for IPv6
Configuring IPv6 NSR support
Use the following commands to configure IPv6 Non-Stop Routing support.
The graceful-restart ipv6 max-hold-timer sets the hold interval.
Brocade(config)#graceful-restart ipv6 max-hold-timer 100
Syntax: [no] graceful-restart ipv6 max-hold-timer hold-interval
The acceptable range for the maximum hold time before sync up forwarding information is 30 to
3600 seconds. The default is 300 seconds.
The graceful-restart ipv6 protocols-converge-timer sets the convergence interval. The default
setting is 5 seconds.
Brocade(config)#no graceful-restart ipv6 protocol-convergence-timer 50
Syntax: [no] graceful-restart ipv6 protocols-converge-timer convergence-interval
The acceptable range for the maximum time for protocols to converge after a graceful restart is 0 to
1200 seconds. The default protocol convergence time is 5seconds.
ECMP load sharing for IPv6
IPv6 ECMP load sharing is hardware-managed. If there is more than one path to a given
destination, a hash is calculated based on the source MAC address, destination MAC address,
source IPv6 address, destination IPv6 address, and TCP/UDP source port and destination port (if
the packet is also a TCP and UDP packet). This hash is used to select one of the paths.
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
To re-enable the feature after disabling it, enter the following command.
Brocade(config)# ipv6 load-sharing 4
Syntax: [no] ipv6 load-sharing number
The number parameter specifies the number of ECMP load sharing paths. Enter a value between 2
and 32 for number to set the maximum number of paths. The default value is 4.
NOTE
The maximum number of paths supported by the BR-MLX-10Gx24-DM module is 16.
