    GRE Tunneling Protocol with IPSec in Network Packet Broker Protect Multicast Data
     
    GRE Tunneling Protocol With IPSec Ethereal Network Sniffer In NPB Protect Multicast Data 0 GRE Tunneling Protocol Identify Technology in Network Packet Broker
    Supported automatically identify various tunneling protocols such as GTP / GRE / PPTP / L2TP / PPPOE. According to the user configuration, the traffic output strategy can be implemented according to the inner or outer layer of the tunnel
     
    What is GRE Tunneling Protocol?
    GRE(Generic Routing Encapsulation)can encapsulate Data packets of some network layer protocols (such as IPX, ATM, IPv6, AppleTalk, etc.)  so that these encapsulated data packets can be transmitted in another network layer protocol (such as IPv4).GRE provides a mechanism for encapsulating messages of one protocol in another. It is a three-layer tunneling technique that allows messages to be transmitted transparently through the GRE tunnel, solving the transmission problem of heterogeneous networks.
    GRE implementation mechanism is simple, the tunnel at both ends of the equipment burden.The GRE tunnel can connect to the local network of various network protocols through the IPv4 network, effectively utilizing the original network architecture and reducing the cost.The GRE tunnel extends the scope of hop-limited network protocols to enable flexible enterprise network topologies.The GRE tunnel can encapsulate multicast data and ensure the security of voice, video and other multicast services when combined with IPSec.GRE tunnel support enables MPLS LDP. GRE tunnel is used to carry MPLS LDP messages, LDP LSP is established, and MPLS backbone network is interoperable.The GRE tunnel connects discrete subnets and is used to set up VPNS for secure connections between corporate headquarters and branches.
     
    The protocol responsible for forwarding encapsulated packets is called the transport protocol.

    GRE header Fields Explain
    C

    Check and verify bits
    The position 1, indicates that the GRE header inserts the Checksum field
    The position 0, indicates that the GRE header does not contain checksum fields

    K

    Keyword bits.
    The position 1, indicates that the GRE header is inserted with a Key field
    The position 0, indicates that the GRE header does not contain keyword fields

    Recursion

    Represents the number of encapsulated layers of a GRE message. Add 1 to this field after completing a GRE package. Discard the text if the number of packages is greater than 3.The purpose of this field is to prevent messages from being encapsulated an infinite number of times.
     
    RFC1701 specifies that the default value for this field is 0.RFC2784 specifies that no exception will be raised if the field is inconsistent between the sender and receiver, and the receiver must ignore the field.
     
    When the device is implemented, this field is only used as the number of nested layers in the tag tunnel when adding the encapsulated message. This field is not perceived when GRE unpacks the message, so it will not affect the processing of the message.

    Flags Reserved fields. Must be set to 0 currently
    Version Version field. It has to be 0
    Protocol Type Identifies the protocol type of passenger agreement. The common passenger protocol is the IPv4 protocol with the protocol code 0x0800
    Checksum Checksum fields for GRE headers and their loads.
    Key Keyword field, the tunnel receiver is used to verify the received message.

     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
    Network Packet Broker Tuneling Label stripping at GRE Application Scenarios 
    1) Multi-protocol local network can be transmitted through this GRE tunnel
    GRE Tunneling Protocol With IPSec Ethereal Network Sniffer In NPB Protect Multicast Data 1
    As shown in the figure above, Term1 and Term2 are local networks running IPv6, while Term3 and Term4 are local networks running IP. Subnetworks in different regions need to communicate with each other through the common IP network.Term1 and Term2, Term3 and Term4 can communicate independently through a tunnel encapsulated in the GRE protocol between Router_1 and Router_2.
     
    2) Use GRE to expand the scope of network work with limited hops
    GRE Tunneling Protocol With IPSec Ethereal Network Sniffer In NPB Protect Multicast Data 2
    In the figure above, the network runs the IP protocol, assuming that the IP protocol limits the number of hops to 255. If the number of hops between two PCS exceeds 255, they will not be able to communicate.Select two devices in the network to create the GRE tunnel, which can hide the number of hops between devices, thus expanding the network's working range.
    For example, a RIP route with 16 hops indicates that the route is unreachable.At this point, the GRE tunnel can be established on the two devices to realize the logical direct connection, so that the RIP routing hops through the GRE tunnel can be reduced to below 16 to ensure the routing is accessible.
     
    3) GRE is combined with IPSec to protect multicast data. IPSec is IP Protocol Security.
    The GRE can encapsulate multicast data and transmit it in the GRE tunnel.
    GRE Tunneling Protocol With IPSec Ethereal Network Sniffer In NPB Protect Multicast Data 3
    As shown in the figure above, in the application of GRE over IPSec tunnel, if multicast data needs to be transmitted in IPSec tunnel, GRE tunnel can be established first, GRE encapsulation of multicast data can be carried out, and then IPSec encryption can be carried out on the encapsulated message, so as to realize encrypted transmission of multicast data in IPSec tunnel.
