Brocade ICX 6650 Layer 3 Routing Configuration Guide 235

OSPF V3 configuration
•155 Mbps port cost = 500/155 = 3.23, which is rounded up to 4
•622 Mbps port cost = 500/622 = 0.80, which is rounded up to 1
•2488 Mbps port cost = 500/2488 = 0.20, which is rounded up to 1
The costs for 10 Mbps, 100 Mbps, and 155 Mbps ports change as a result of the changed
reference bandwidth. Costs for higher-speed interfaces remain the same.
Syntax: [no] auto-cost reference-bandwidth number
The number parameter specifies the reference bandwidth and can be a value from 1 – 4294967.
The default is 100.
To restore the reference bandwidth to its default value and thus restore the default costs of
interfaces to their default values, enter the no form of this command.
Redistributing routes into OSPF V3
In addition to specifying which routes are redistributed into OSPF V3, you can configure the
following aspects related to route redistribution:
•Default metric
•Metric type
•Advertisement of an external aggregate route

Configuring route redistribution into OSPF V3

You can configure the Brocade device to redistribute routes from the following sources into OSPF
V3:
•IPv6 static routes
•Directly connected IPv6 networks
•RIPng
You can redistribute routes in the following ways:
•By route types, for example, the Brocade device redistributes all IPv6 static and RIPng routes.
•By using a route map to filter which routes to redistribute, for example, the Brocade device
redistributes specified IPv6 static and RIPng routes only.
For example, to configure the redistribution of all IPv6 static RIPng routes, enter the following
commands.
Brocade(config-ospf6-router)#redistribute static
Brocade(config-ospf6-router)#redistribute rip
Syntax: [no] redistribute bgp | connected | rip | static [metric number | metric-type type]
The connected | rip | static keywords specify the route source.
The metric number parameter specifies the metric used for the redistributed route. If a value is not
specified for this option, and the value for the default-metric command is set to 0, its default
metric, then routes redistributed from the various routing protocols will have the metric value of the
protocol from which they are redistributed. For information about the default-metric command,
refer to “Modifying default metric for routes redistributed into OSPF V3” on page237
