Factors Assisting Protocol Convergence
Keep number of routing devices in each topology area small (15 – 20 or so)
- Reduces convergence time required
Avoid complex meshing between devices in an area
- Two links are usually all that are necessary
Keep prefix count in interior routing protocols small
- Large numbers means longer time to compute shortest path
Use vendor defaults for routing protocol unless you understand the impact of “twiddling the knobs”
- Knobs are there to improve performance in certain conditions only
