Sorry for the lack of updates this week. I’ve just moved into a new place and I haven’t had time to get anything written up. I’m also lacking ideas lately, so leave some comments if you guys have any requests or ideas.

The answer to the fifth question has been added to the post.

Sixth question:

What is “stuck in active” (SIA), what protocol does it affect and how is it prevented?


Please post answers in the comments (without Googling)!


Highlight for answer:

SIA affects EIGRP. It happens when a router queries all of it’s EIGRP neighbors looking for a replacement route and is stuck waiting for replies. Some ways to prevent SIA are to use summary routes and/or stub networks.
