Question

What is the purpose of the configuration config ipsec vpn phase1-interface edit set aggregate-member enable set aggregate-weight [L3 | L4 | redundant | weighted round robin] next end?

a) Configures IPSec tunnel aggregation settings
b) Sets IPSec tunnel priority
c) Initiates IPSec VPN routing
d) Defines IPSec VPN authentication modes

Answer 1

The command in question configures IPSec tunnel aggregation settings, allowing the management of multiple IPSec VPN tunnels through methods such as load balancing and redundancy for optimized traffic distribution.

Step-by-step explanation:

The command config ipsec vpn phase1-interface is used in network configurations to manage the settings of an IP Security (IPSec) Virtual Private Network (VPN) phase 1 interface on a network device such as a firewall or router. Specifically, this configuration snippet:

• Enables the aggregation of IPSec tunnels with the set aggregate-member enable command.
• Sets the method for distributing traffic among the aggregated tunnels with the set aggregate-weight command, where the options include load balancing based on Layer 3 or Layer 4 information, favoring a redundant path, or using a weighted round-robin algorithm.

In short, the primary purpose of this configuration is to configure IPSec tunnel aggregation settings for better management of multiple VPN tunnels that connect network segments over an IPSec VPN.
