Question 369 - 300-415 discussion

To achieve communication between Barcelona and Paris through the London site, a control policy needs to be configured to force traffic from these two sites to pass through the London site. This setup involves manipulating the routing information such that London becomes a transit hub for traffic between Barcelona and Paris.

1.Understanding the Policy Requirements:

oCentralized Policy: This type of policy is applied at the controller level and affects multiple devices in the SD-WAN fabric. It allows the control of routing behavior across the entire network.

oRoute Policy: Specifically, a route policy will be used to set the preferred path for traffic between sites, ensuring that it passes through London.

1.Option Analysis:

oOption A: Shows the configuration of a centralized policy with a focus on route policy, which is necessary to achieve the desired traffic flow manipulation.

oOther Options: Do not provide the necessary centralized policy or route policy configurations that are needed to control the routing paths between the sites.

1.Configuration Details:

oCentralized Policy: Define the policy under the centralized policy section in the vManage GUI.

oRoute Policy: Create and apply a route policy that specifies the desired routing behavior for traffic between Barcelona and Paris, ensuring it routes through London.
