Exam JN0-104 topic 1 question 16 discussion

the no-readvertise option, which prohibits redistribution of the route by the routing policy in a dynamic routing protocol such as OSPF. We strongly recommend that you use the no-readvertise option on static routes that direct traffic to the traffic to the management Ethernet interface and the management network. the no-readvertise option restricts route from being advertised into a routing protocol through routing policy; Strongly recommended for static routes used for management traffic

In order to prevent the redistribution of a static route using a dynamic routing protocol in Junos OS, the configuration parameter that can accomplish this task is: A. no-readvertise By using the "no-readvertise" parameter, you can prevent the static route from being redistributed into any dynamic routing protocols that are configured on the router. This parameter ensures that the static route is not advertised to other routers through the dynamic routing protocol. So, option A, "no-readvertise," is the correct configuration parameter to achieve the desired result.

Ref: keep static route from being redistributed into dynamic routing protocols | Junos OS Post by pevangelista “… Here's an excerpt from Juniper's documentation on readvertise: Static routes are eligible to be readvertised (that is, exported from the routing table into dynamic routing protocols) if a policy to do so is configured. To mark an IPv4 static route as being ineligible for readvertisement, include the no-readvertise statement.”
