Configuring OSPFv3
NOTE
This option affects only imported, type 5 external routes. A single type 5 LSA is generated and
flooded throughout the AS for multiple external routes.
To configure the summary address 2001:db8::/24 for routes redistributed into OSPFv3, enter the
following command.
Brocade(config-ospf6-router)# summary-address 2001:db8::/24
In this example, the summary prefix 2001:db8::/24 includes addresses 2001:db8::/1 through
2001:db8::/24. Only the address FEC0::/24 is advertised in an external link-state advertisement.
Syntax: summary-address ipv6-prefix/prefix-length
You must specify the ipv6-prefix parameter in hexadecimal using 16-bit values between colons as
documented in RFC 2373.
You must specify the prefix-length parameter as a decimal value. A slash mark (/) must follow the
ipv6-prefix parameter and precede the prefix-length parameter.
Filtering OSPFv3 routes
You can filter the routes to be placed in the OSPFv3 route table by configuring distribution lists.
OSPFv3 distribution lists can be applied globally or to an interface.
The functionality of OSPFv3 distribution lists is similar to that of OSPFv2 distribution lists. However,
unlike OSPFv2 distribution lists, which filter routes based on criteria specified in an Access Control
List (ACL), OSPFv3 distribution lists can filter routes using information specified in an IPv6 prefix list
or a route map.
Configuration examples
The following sections show examples of filtering OSPFv3 routes using prefix lists globally and for a
specific interface, as well as filtering OSPFv3 routes using a route map.
You can configure the device to use all three types of filtering. When you do this, filtering using
route maps has higher priority over filtering using global prefix lists. Filtering using prefix lists for a
specific interface has lower priority than the other two filtering methods.
The example in this section assumes the following routes are in the OSPFv3 route table.
