Introduction of GRE VPN of S switches
Introduction to GRE of S series switches excluding the S1700: Generic Routing Encapsulation (GRE) encapsulates packets of some network-layer protocols, such as Internetwork Packet Exchange (IPX), IPv6, and AppleTalk, so that the encapsulated packets can be transmitted over networks of a different network-layer protocol, such as the IPv4 network. As a Layer 3 tunneling technology, GRE encapsulates packets of a protocol into packets of another protocol to transparently transmit packets over GRE tunnels. This technology enables packet transmission on heterogeneous networks. GRE is easy to implement, imposing low burden on devices on both ends of a tunnel. GRE tunnels can connect networks running various network protocols over the IPv4 network, using the original network architecture and reducing costs. GRE extends the operation scope of network protocols with limited hop counts, allowing for flexible enterprise networking. GRE connects discontinuous subnets and sets up VPNs, implementing secure connections between the enterprise headquarters and branches.

OSN 3500 II
The OSN 3500 II is a new generation intelligent optical switching system developed by Huawei. It applies to the network convergence layer for grooming and transmitting services such as SDH, PDH, Ethernet, ATM, and DDN. By using intelligent network technologies, the system manages services and bandwidths intelligently. It supports an embedded microwave IF board which works with the ODU of Huawei microwave device to achieve wireless service transmission. Currently, the system supports 110 Gbit/s higher-order cross-connections and 20 Gbit/s lower-order cross-connections. A single subrack of the system supports up to 90 Gbit/s access capability, and the microwave IF interface provided by the system offers 18 microwave directions.

How to Introduce Default Routes for USG2000 & USG2000 Series OSPF?
The USG2000 series configuration OSPF introduces the default route as follows: 1. Run the system-view command in the user view to enter the system view. 2. Run: ospf [process-id] The OSPF view is displayed. 3. Select the following configuration according to the actual situation. If you want to redistribute the default route into the OSPF process, run the default-route-advertise [[all | permit] | cost type | type type | route-policy route-policy-name] If you want to specify the default cost of the Type-3 summary LSA, run the default-route-advertise summary cost cost command.
