Link State updates - how often should they occure. The text book says a link state update should occur only when a rotuer detects a missing piece in its database or when topology changes. This would mean to me then that in a stable network, link state updates should occure very infrequently. While playing with the "show ip traffic" command this morning I noticed one of the outputs to this was the following:
Rcvd: 9279 total, 0 checksum errors
7306 hello, 37 database desc, 12 link state req
1003 link state updates, 921 link state acks
Sent: 4948 total
3662 hello, 44 database desc, 7 link state req
945 link state updates, 294 link state acks
I've noticed that the link state updates counter is increasing.
Does this mean routing instability of some sort in my network? As I check around my network I do not see routes coming and going so I'd like to understand what those mean and if they are normal in a stable network.
