Configuring IS-IS to use an MD5 algorithm compatible with the switches ofother manufacturersTo enable IS-IS MD5 authentication between the switch and the switches of othermanufacturers, you must use the following commands to configure IS-IS to use anMD5 algorithm compatible with the switches of other manufacturers.Follow these steps to configure IS-IS to use an MD5 algorithm compatible with theswitches of other manufacturers:To do...

This can cause repeated LSP flooding on a high-connectivitynetwork with multiple point-to-point links, which is a waste of the bandwidth.To avoid this problem, you can add interfaces into a mesh group. The interfaces in thegroup will flood the new LSPs to only the interfaces outside the mesh group.Follow these steps to add an interface to a mesh group:
