Overview
Use this command in Router Configuration mode to summarize, or possibly
suppress, external redistributed OSPFv3 routes within the specified address range.
Use the no variant of this command in Router Configuration mode to stop
summarizing, or suppressing, external redistributed OSPFv3 routes within the
specified address range.
summary-address <ipv6-addr/prefix-length> [not-advertise] [tag
Syntax
<0-4294967295>]
no summary-address <ipv6-addr/prefix-length> [not-advertise]
[tag <0-4294967295>]
Default
The default tag value for a summary address is 0.
Mode
Router Configuration
Usage
An address range is a pairing of an address and a prefix length. 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 prefix to decrease the size
of the OSPFv3 link state database.
For example, if the specified address range is 2001:0db8:44::/48, then
summary-address functionality will match 2001:0db8:4400:0000::1/128 through
2001:0db8:44ff:ffff::1/128.
Ensure OSPFv3 routes exist in the summary address range for advertisement
before using this command.
