Frequently Asked Questions
What is EIGRP?
Enhanced Interior Gateway Routing Protocol is an advanced distance-vector protocol that uses the DUAL algorithm for fast, loop-free convergence. It was Cisco-proprietary before being partially opened.
What is a feasible successor?
A feasible successor is a backup route that is guaranteed loop-free, so EIGRP can switch to it instantly if the primary fails, without recomputing.
What is route redistribution?
Redistribution shares routes between routing protocols, for example EIGRP and OSPF. Done carelessly it causes loops or leaks routes, which this free Codelivly room helps you avoid.
