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
.

Comprehensive and Detailed Step-by-Step Explanation:
* Interface ID in IPv6:
* The interface ID is the last 64 bits of an IPv6 address, and it uniquely identifies an interface within a subnet.
* It can be generated in three ways:
* Manually Configured: Explicitly assigned by an administrator.
* System-Generated: The operating system assigns a random or pseudo-random value.
* EUI-64 Standard: Generated based on the MAC address of the interface.
* Correct Statement:
* IPv6 supports all three methods for generating interface IDs.

Let me continue with the next batch of questions!

BFD (Bidirectional Forwarding Detection)is a lightweight protocol that providesrapid detectionof faults in the forwarding path between two routers or switches.
It worksin conjunction with routing protocolsand provides fast failure detection to enable quick route convergence.
Protocol support:
B: BFD for static routes- Supported. BFD tracks the reachability of next-hop addresses and can trigger route removal upon failure.
C: BFD for OSPF- Supported. BFD can be associated with OSPF to accelerate the detection of neighbor failures.
D: BFD for BGP- Supported. BFD enables sub-second detection of BGP peer failures.
A: BFD for PIM-Not supported. PIM (Protocol Independent Multicast) typically does not use BFD for neighbor failure detection.
Reference from Huawei HCIP-Datacom-Core Technology Study Guide:
"BFD can be associated with static routes, OSPF, IS-IS, BGP, and other protocols to quickly detect link or device faults and trigger fast rerouting." (Chapter: High Availability Technologies - Section: BFD Principles and Applications)

The defaultSTP priorityon Huawei switches (and in the IEEE standard) is32768.
Lower priority values increase the likelihood of a switch becoming the root bridge. You can configure this value in increments of 4096.
Reference from Huawei HCIP-Datacom-Core Technology Study Guide:
"The default bridge priority of Huawei switches is 32768. The root bridge is elected based on the lowest bridge ID, which consists of the priority and MAC address." (Chapter: Spanning Tree Protocols - Section: RSTP and Bridge Election)
