300-415 Question 134
Single answerA network engineer is configuring OMP (Overlay Management Protocol) in a Cisco SD-WAN environment. The engineer wants to ensure that only specific routes are advertised to remote sites. Which configuration approach should they take to achieve this?
- A
Use a centralized control policy to filter and advertise specific routes.
- B
Enable OMP graceful restart on all vEdge routers.
- C
Modify the OMP timers to reduce route advertisement intervals.
- D
Configure a local policy on each vEdge router to filter OMP routes.
Show answer and explanation
Correct answer: A
Explanation
In a Cisco SD-WAN deployment, centralized control policies are the recommended method to filter and manipulate OMP route advertisements. These policies are configured on the vSmart controllers, allowing consistent and scalable route management across the SD-WAN fabric.
- A. Correct.
Centralized control policies are used to filter and manipulate OMP route advertisements across the SD-WAN fabric. This allows the network administrator to define policies centrally and apply them consistently.
- B. Incorrect.
OMP graceful restart ensures stability during control plane reconvergence but does not control route advertisements.
- C. Incorrect.
Modifying OMP timers affects the frequency of updates but does not filter or restrict specific routes from being advertised.
- D. Incorrect.
Local policies on vEdge routers can manage routing locally but are not suitable for defining centralized route advertisement policies across the network.
