protocols ospfv3 summary-address <address> <action>
Summarizes or suppresses external routes with a specified address range.
Routing updates are not suppressed.
- process-id
- An OSPFv3 process ID. Enter alphanumeric characters.
- ip6net
- A range of addresses given as IPv6 starting address and a mask.
- ipv4net
- A range of addresses given as IPv4 starting address and a mask.
- not-advertise
- Suppresses routes that match a range.
- tag-value
- Tag value to use as a “match” value for controlling redistribution via route maps. Set a tag value. The tag value ranges from 0 to 4294967295. The default is 0.

}Use this command to summarize or suppress external routes with a specified address range.
An address range is a pairing of a starting address and a mask that is almost the same as IP network number. For example:
- If the specified IPV6 address range is 2020:100:100:2000::/53, it matches 2020:100:100:2222::/64, 2020:100:100:2666::/64 and so on.
- If the specified IPV4 address range is 192.168.0.0/255.255.240.0, it matches 192.168.1.0/24, 192.168.4.0/22, 192.168.8.128/25 and so on.
Redistributing routes from other protocols into OSPFv3 requires the router to advertise each route individually in an external LSA. Use this command to advertise one summary route for all redistributed routes covered by a specified network address and mask. This minimizes the size of the OSPFv3 link state database.
