• IPv6 static routes
• Directly connected IPv6 networks
You can redistribute routes in the following ways:
• By route types, for example, the Brocade device redistributes all IPv6 static routes.
• By using a route map to filter which routes to redistribute, for example, the Brocade device
redistributes specified IPv6 static routes only.
For example, to configure the redistribution of all IPv6 static routes, enter the following commands:
Virtual ADX(config-ospf6-router)# redistribute static
Syntax: [no] redistribute connected | static [metric number | metric-type type]
The connected | 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 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 version 3” on page 161
The metric-type type parameter specifies an OSPF metric type for the redistributed route. You can
specify external type 1 or external type 2. If a value is not specified for this option, the Brocade
device uses the value specified by the metric-type command. For information about modifying the
default metric type using the metric-type command, refer to
“Modifying default metric for routes
redistributed into OSPF version 3” on page 161
For example, to configure a route map and use it for redistribution of routes into OSPFv3, enter
commands such as the following:
Virtual ADX(config)# ipv6 route 2001:db8:1::/32 2001:db8:4823:eoff:343e::23
Virtual ADX(config)# ipv6 route 2001:db8:2::/32 2001:db8:4823:eoff:343e::23
Virtual ADX(config)# ipv6 route 2001:db8:3::/32 2001:db8:4823:eoff:343e::23
metric 5
Virtual ADX(config)# route-map abc permit 1
Virtual ADX(config-routemap-abc)# match metric 5
Virtual ADX(config-routemap-abc)# set metric 8
Virtual ADX(config-routemap-abc)# ipv6 router ospf
Virtual ADX(config-ospf6-router)# redistribute static route-map abc
The commands in this example configure some static IPv6 routes and a route map, and use the
route map for redistributing the static IPv6 routes into OSPFv3.
The ipv6 route commands configure the static IPv6 routes.
The route-map command begins configuration of a route map called “abc”. The number indicates
the route map entry (called the “instance”) you are configuring. A route map can contain multiple
entries. The software compares packets to the route map entries in ascending numerical order and
stops the comparison once a match is found.
The match command in the route map matches on routes that have 5 for their metric value (cost).
The set command changes the metric in routes that match the route map to 8.
The redistribute command configures the redistribution of static IPv6 routes into OSPFv3, and uses
route map “abc“ to control the routes that are redistributed. In this example, the route map allows a
static IPv6 route to be redistributed into OSPF only if the route has a metric of 5, and changes the
metric to 8 before placing the route into the OSPF route redistribution table.
