external routes at the border of the OSPF domain. The no version restores the default.
Options

the summary route

1; when distributing routes domain wide, summarizes routes leaked
from level 2 into level 1
level-1-2—Summarizes routes redistributed into level
1 and level 2 IS-IS, and routes leaked between levels
level-2—Summarizes routes learned by level 1 routing
into the level 2 backbone with the configured address/mask value;
also summarizes routes redistributed into level 2 IS-IS

value when advertising the summary address. When no metric is supplied,
