1. What action does a link-state router take immediately upon receipt of an LSP from a neighboring router?

floods the LSP to neighbors

calculates the SPF algorithm

runs the Bellman-Ford algorithm

computes the best path to the destination network


2. Why is it difficult for routing loops to occur in networks that use link-state routing?

Each router builds a simple view of the network based on hop count.

Routers flood the network with LSAs to discover routing loops.

Each router builds a complete and synchronized view of the network.

Routers use hold-down timers to prevent routing loops.
