Configuring OSPFv3
• The bandwidth for tunnel interfaces is 9 Kbps and is subject to the auto-cost feature.
For example, to change the reference bandwidth to 500, enter the following command.
Brocade(config-ospf6-router)# auto-cost reference-bandwidth 500
The reference bandwidth specified in this example results in the following costs:
• 10 Mbps port cost = 500/10 = 50
• 100 Mbps port cost = 500/100 = 5
• 1000 Mbps port cost = 500/1000 = 0.5, which is rounded up to 1
• 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 in the range from 1 through 4294967.
The default is 100.
To restore the reference bandwidth to its default value and thus restore the default costs of the
interfaces to their default values, enter the no form of this command.
Redistributing routes into OSPFv3
In addition to specifying which routes are redistributed into OSPFv3, you can configure the following
aspects related to route redistribution:
• Default metric.
• Metric type.
• Advertisement of an external aggregate route.
Configuring route redistribution into OSPFv3
You can configure the device to redistribute routes from the following sources into OSPFv3:
• IPv6 static routes
• Directly connected IPv6 networks
• BGP4+
• IPv6 IS-IS
• RIPng
You can redistribute routes in the following ways:
• By route types, for example, the device redistributes all IPv6 static and RIPng routes.
• By using a route map to filter which routes to redistribute, for example, the device redistributes
specified IPv6 static and RIPng routes only.
