Figure 6-215 ISIS Router Settings (Summary Address List) Window The fields that can be configured are described below: Parameter Summary Address Description Select the level and enter the summary addresses here. This is used to create aggregate addresses for ISIS. Multiple groups of addresses can be summarized for a given level. Routes learned from other routing protocols can also be summarized. The metric used to advertise the summary is the smallest metric of all the more specific routes. This command helps reduce the size of the routing table. This command also reduces the size of the link-state packets (LSPs) and thus the link-state database (LSDB). It also helps network stability because a summary advertisement is depending on many more specific routes. A single route flap does not cause the summary advertisement to flap in most cases. The drawback of summary addresses is that other routes might have less information to calculate the most optimal routing table for all individual destinations. Levels to choose from are: Level-1 - Specifies that only routes redistributed into level 1 are summarized with the configured IP address and mask value. Level-1-2 - Specifies that summary routes are applied when redistributing routes into level 1 and level 2 ISIS and when level 2 ISIS advertises level 1 routes as reachable in its area. Level-2 - Specifies that routes learned by level 1 routing are summarized into the level 2 backbone with the configured IP address and mask value. Redistributed routes into level-2 ISIS will be summarized also. Click the Apply button to accept the changes made. Click the Back button to return to the previous window.
