Question

A network engineer is configuring Cisco Catalyst SD-WAN application-aware routing for a branch that has two transport tunnels: a low-latency MPLS (color 'mpls') and a broadband internet link (color 'biz-internet'). Business requirement: interactive video traffic must always prefer the MPLS tunnel, but if MPLS violates the SLA class (loss > 2%, latency > 150 ms), traffic should immediately move to biz-internet. If both tunnels violate the SLA, traffic must continue to flow rather than be dropped. Which application-aware route policy configuration meets all requirements?

Accepted Answer

Define an SLA class with the loss/latency thresholds, set 'preferred-color mpls', and enable the 'sla-class preferred-color' with default behavior so traffic falls back to any available tunnel when all colors violate the SLA.

Answer

Define an SLA class with the thresholds and set the action to 'strict' so that traffic is dropped when no tunnel meets the SLA, ensuring only compliant paths are used.

Answer

Configure a centralized control policy with 'set service' to steer video traffic to MPLS and rely on OMP to withdraw the route when MPLS latency rises.

Answer

Configure a local data policy on the branch router with 'set next-hop' pointing to the MPLS tunnel interface and a backup static route to biz-internet.
