Juniper JN0-363 Exam Dumps

The AS path is a BGP attribute that lists the autonomous systems (AS) that routing information has passed through to get to a destination. It is used to detect and prevent routing loops by checking if the router's own AS number is in the path.

Juniper Networks documentation on BGP: BGP Attributes and Policy

In a service provider MPLS network, P routers are interior routers that are used to transit MPLS-labeled packets between edge routers but do not attach or remove MPLS labels themselves. These routers are also referred to as transit routers. They are neither ingress nor egress routers (which are typically labeled as PE routers).

Referring to the configuration in the exhibit, R1 is set to export the 3rd_Policy to the neighbor at 192.168.1.5. Since 3rd_Policy permits the 10.200.3.0/24 prefix, only that prefix will be advertised to the neighbor. Reference::

only 10.200.3.0/24 will be advertised. The neighbor export overrides anything at the group level and protocol level. Policies aren't additive, you can't apply all three at the same time. What if one of them rejected a prefix while the other accepted the same one? You need one to override the other

The no-readvertise policy statement is used to prevent a static route from being redistributed into a dynamic routing protocol. This setting ensures that routes that are configured statically are not advertised out via dynamic routing protocols such as OSPF or BGP.

Filter-based forwarding in Junos requires the creation of a routing policy to specify the match conditions and actions and the application of a match filter to classify traffic to use the policy. Reference::
