Description

Currently, we say:

"You can have up to 128 interior routers in the router network."

and 

"Because there are no limits to the number of edge routers deployed..."

Remove these mentions and  add:

Performance of your router network is determined by various factors:

• topology
• number of routers
• underlying infrastructure (host resources, network speed, etc)

It is recommended to implement an architecture that minimises the number of routers to maintain satisfactory performance.
