Juniper JN0-363 Exam With Confidence Using Practice Dumps

The exhibit shows an aggregate route configuration for the network172.21.0.0/22, which would summarize the specific networks172.21.0.0/24,172.21.1.0/24, and172.21.2.0/24. For an aggregate route to be active, it must have contributing routes in the routing table. If the route is hidden, it usually means there are no contributing routes that are active or the policy applied to the aggregate does not match any of the specific routes.Therefore, the first step in troubleshooting would be to verify that there are indeed active contributing routes for the aggregate to be valid.

Segment routing labels can be distributed by link-state routing protocols such as IS-IS and OSPF, which have been extended to support segment routing capabilities.References:

In an MPLS network, the types of routers include ingress routers (where the MPLS labels are first applied), egress routers (where MPLS labels are removed), and transit routers (which switch MPLS-labeled packets through the MPLS network). Peering routers andaggregation routers are not specific types of MPLS routers; they are general network terms.
