Comprehensive and Detailed Step-by-Step Explanation:
1. Understanding IGMP (Internet Group Management Protocol):
* IGMP is used in multicast networking to manage membership of devices in multicast groups.
* Key parameters in the configuration provided:
* Interface IP Address: 192.168.1.1
* IGMP Version: 2
* Query Interval (Configured): 60 seconds
* Maximum Query Response Time: 10 seconds
* Querier Address: 192.168.1.1
2. Analysis of Each Statement:
Option A: The IP address of the interface is 192.168.1.1.
* Correct (True Statement).
* The configuration clearly shows that the IP address of the interface is 192.168.1.1.
Option B: The maximum response time to Query messages is 10s.
* Correct (True Statement).
* The configuration explicitly mentions: Value of maximum query response time for IGMP: 10 s.
Option C: The interval for sending Group-Specific Query messages is 60s.
* Incorrect (False Statement).
* The 60-second value refers to the query interval, which is the time interval between general queries sent by the querier.
* The interval for group-specific queries is not specified in this configuration. It is determined dynamically based on the multicast environment and is usually shorter than the general query interval.
Option D: The IGMP version is IGMPv2.
* Correct (True Statement).
* The configuration specifies: Current IGMP version is 2.
3. Why Option C is False:
* The 60-second value is for general query interval, not group-specific query interval.
* The statement misinterprets the configuration, making it false.
4. Summary:
C: (The interval for sending Group-Specific Query messages is 60s).

Comprehensive and Detailed Step-by-Step Explanation:
* Route Policy Overview:
* A route-policy is a policy-based routing tool that filters and modifies routing information.
* It consists of one or more nodes, and each node can specify match conditions and apply actions to routes.
* Maximum Number of Nodes:
* The maximum number of nodes supported in a route-policy is 1024, allowing flexibility in route filtering and control.

The default sending interval for BFD (Bidirectional Forwarding Detection) control packets is 100 milliseconds. This interval ensures rapid detection of link faults, providing fast failover and minimizing downtime in network operations .

The virtual MAC address for a VRRP virtual router is determined by the formula 00-00-5E-00-01-[VRID in hexadecimal]. For VRID 3, the hexadecimal equivalent is 03. Thus, the virtual MAC address is 00-00-5E-00-
01-03 .

Comprehensive and Detailed Step-by-Step Explanation:
* VRRP Virtual MAC Address Format:
* The VRRP virtual MAC address is generated using the format:0000-5e00-01XX, where XX represents the VRID in hexadecimal.
* Calculation:
* VRID = 1 # Hexadecimal = 01.
* Virtual MAC = 0000-5e00-0101.
* Correct Option:
* C (0000-5e00-0101).
