GRE (Generic Routing Encapsulation) over IPsec is a technique to securely transmit encapsulated network packets using the IPsec protocol for encryption and integrity protection.
GRE over IPsec Definition: GRE (Generic Routing Encapsulation) over IPsec is a technique to securely transmit encapsulated network packets using the IPsec protocol for encryption and integrity protection.
GRE (Generic Routing Encapsulation) over IPsec is a method of combining the GRE tunneling protocol with the IPsec encryption protocol to create a secure communication channel. GRE is used to encapsulate and route different types of network traffic over a secure IPsec tunnel, providing both encapsulation for multiple protocols and encryption for secure data transfer. This combination allows for the secure transmission of data between network devices or across the internet, ensuring the confidentiality and integrity of the transmitted information.
