In this blogtorial we are going to see how we can configure MPLS Traffic Engineering (MPLS TE). With MPLS TE we can achieve SONET (50ms) style failover between links and we can achieve this by creating backup tunnels and using fast re-route.
In this topology we will be configuring both explicit/static tunnels/paths and also dynamic auto-tunnels.
Consider the simple topology below and let's get started.
Relevant configurations are posted below.
