sql
Copy
<HUAWEI> display igmp group
Interface group report information
Vlanif100(10.1.6.2):
Total 1 IGMP Group reported
Group Address Last Reporter Uptime Expires
225.1.1.2 10.1.6.10 00:02:04 00:01:17
Given this, which of the following statements are true?

A. 225.1.1.2 is the address of the group that the user joins.
B. Expires indicates the aging time of the IGMP group.
C. This entry can be used to construct the corresponding (S, G) entry.
D. This entry is created when the device receives an IGMP Join message from a user.

Answer: A,B,D

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. Understanding the IGMP Group Entry:
The IGMP group entry contains key information about multicast groups on the interface:
Group Address (225.1.1.2):The multicast group address that the user has joined.
Last Reporter (10.1.6.10):The IP address of the last host that sent an IGMP Report message for this group.
Uptime:The duration since the group was first reported.
Expires:The remaining time before the group entry ages out if no further reports are received.
2. Analysis of Each Statement:
Option A: This entry can be used to construct the corresponding (S, G) entry.
Incorrect.
This is a group entry for IGMP, which contains information about the group (G) but does not include a specific source (S). (S, G) entries are created in PIM (Protocol Independent Multicast), not IGMP.
Option B: This entry is created when the device receives an IGMP Join message from a user.
Correct.
IGMP Join messages are used by hosts to signal their intent to join a multicast group. When such a message is received, the group entry is created.
Option C: Expires indicates the aging time of the IGMP group.
Correct.
The "Expires" field shows the remaining time before the group entry ages out if no further IGMP reports are received.
Option D: 225.1.1.2 is the address of the group that the user joins.
Correct.
The "Group Address" field explicitly states that 225.1.1.2 is the multicast group that the user has joined.
3. Summary:
Correct Options:B, C, D
Reference:
Huawei HCIA-Datacom Study Guide, Chapter "IGMP Group Entries."
