Question: What is a potential consequence of including a SEG CA certificate in the IKE packet for Ethernet environments, according to network security considerations?
Option 1: Increased security due to enhanced authentication
Option 2: Fragmentation of the IKE packet, potentially causing interoperability issues with some current IKE implementations
Option 3: Automatic protocol upgrade to resolve compatibility problems
Option 4: Mandatory use of IPv6 to bypass Ethernet limitations
Explanation: Including a SEG CA certificate in the IKE packet can lead to packet fragmentation in Ethernet environments. This is problematic because some current IKE implementations do not support fragmented packets, leading to potential interoperability issues.
