PBR is a mechanism for routing selection based on user-defined strategies

Through PBR, you can set the routing attributes imported by the routing protocol

NEW QUESTION 16
B As shown in the figure, RTA, RTB, and RTC run OSPF, and the process number is 100; OSPF process 200 runs between RTA, RTB, and RTD. The cost of all interconnected links is set to 10. Set the external route priority of OSPF 100 on RTA and RTB to 190, and import an external route 172.16.1.0/24 into OSPF 100 on RTC. Both RTA and RTB are configured to import OSPF100 routes into OSPF200.
According to the above scenario analysis, the following description about RTD learning external routing 172.16.1.0/24 is correct.

There are two equal-cost routes to 172.16.10.0/24 on RTD, and the next hop points to RTA and RTB respectively

There is a route to 172.16.10.0/24 on RTD, and the next hop must point to RTA

The route of 172.16.10.0/24 cannot be learned on RTD

There is a route to 172.16.10.0/24 on RTD, and the next hop may point to RTA or RTB

NEW QUESTION 17
Regarding IS-IS and OSPF networking and applicable scenarios, the following description is correct.

The backbone area number of OSPF must be 0 and be continuous, and its continuity can be ensured through virtual connections

IS-IS backbone area consists of all Level-2 and Level-1-2 systems. Because there is no virtual connection, it must be physically continuous

IS-IS protocol messages are in TLV format, which is easy to extend to support various network protocols, such as IPv6; while OSPFv2 protocol messages are based on IP and are too tightly integrated with IPv4, so it is difficult to extend support for IPv6

Although both support large-scale hierarchical networks, OSPF is more widely used in enterprise-level networks

NEW QUESTION 18

NET can be regarded as the NSAP address with NSEL being 0
