Use ipv6 summary to configure an IPv6 IS-IS summary route.
Use undo ipv6 summary to remove the summary route.
Route summarization is disabled by default.
Configuring summary routes can reduce the size of the route table, LSPs and LSDB. Routes to be
summarized can be IS-IS routes or redistributed routes. The cost of a summary route is the smallest
cost among all summarized routes.
