NEW QUESTION # 360
BGP selects routes by comparing route attributes in sequence. When a route attribute alone helps determine the optimal route, BGP does not compare subsequent attributes. Which of the following attributes is compared first during BGP route selection?

A. AS_Path
B. Local_Pref
C. Origin
D. PrefVal

Answer: D

Explanation:
BGP selects the optimal route by evaluating path attributes according to a defined priority sequence. Before comparing path attributes, BGP checks whether the next-hop address is reachable. Routes with unreachable next hops are excluded from preferred-route selection.
Among the listed attributes, PrefVal (Preferred-Value) has the highest selection priority on Huawei devices.
According to the HCIP-Datacom-Core Technology training material, BGP compares the attributes in the following relevant order:
* Preferred-Value - highest value preferred.
* Local_Preference - highest value preferred.
* Locally originated routes.
* AS_Path - shortest path preferred.
* Origin - IGP preferred over EGP and Incomplete.
PrefVal is a Huawei-specific, locally significant attribute and is not advertised to BGP peers. If PrefVal determines the best route, subsequent attributes are not compared.
Therefore, option D is correct.

A. The route to the destination address 192.168.1.0 is injected into the BGP routing table using the network command.
B. The route to the destination address 192.168.1.0 is not the optimal route in the BGP routing table.
C. The route to the destination address 192.168.1.0 is learned through AS 200.
D. The MED value of the route to the destination address 192.168.1.0 is 100.

Answer: A

Explanation:
The Origin attribute in the display bgp routing-table output is marked as i, indicating that the route was injected into the BGP routing table using the network command. The other options are incorrect because the AS path is not displayed, the MED is 0, and the route is marked as the best (>), meaning it is the optimal route
.
