In the exhibit, the output of the `show route protocol bgp` command is shown for the prefix `172.16.20.4/30`. Let's analyze the provided BGP routing table to determine which statements are correct.
1. **AS Path Analysis**:
- The AS path for the route `172.16.20.4/30` is shown as `2 I`.
- This indicates that the route was learned from AS 2 and it is an internal (iBGP) route within the same AS.
2. **Multiple Paths**:
- The route has two next-hop IP addresses: `10.0.18.2` via interface `ge-1/0/4.0` and `10.0.19.2` via interface `ge-1/0/5.0`.
- This indicates that BGP multipath is configured, which allows multiple equal-cost paths to be used for load balancing.
- BGP multipath must be explicitly configured to use multiple paths for the same prefix.
3. **Multihop vs. Multipath**:
- **Multihop Configuration**: This is typically used for establishing BGP sessions with peers that are not directly connected. It is not related to load balancing.
- **Multipath Configuration**: This is used to enable load balancing across multiple paths for the same prefix, which is the case here.
**Conclusion**:
Given the above analysis:
- **C. This route is learned from the same AS number**: Correct. The AS path `2 I` indicates the route was learned from the same AS number (AS 2).
- **D. The multipath configuration is used for load balancing**: Correct. The presence of multiple next-hops indicates that BGP multipath is configured for load balancing.
Thus, the correct answers are:
**C. This route is learned from the same AS number.**
**D. The multipath configuration is used for load balancing.**
