In-Depth Information
Occasional messages of this type are not a cause for concern. This is how an Enhanced
IGRP router recovers if it does not receive replies to its queries from all its neighbors.
However, if these error messages occur frequently, you should investigate the problem.
Note
For a more detailed explanation of Enhanced IGRP active mode, see the section “Enhanced IGRP and
Active/Passive Modes,” later in this chapter.
