摘要： In an example, a VTEP device may store first routing information acquired by the VTEP device, wherein the first routing information may be routing information of a host device connected with the VTEP device. The VTEP stores second routing information sent from other VTEP devices in a VXLAN, wherein the second routing information may be routing information of a host device connected with the other VTEP devices. The VTEP receives an address resolution request from a source host device, wherein the address resolution request comprises an IP address of a target host device, and a VXLAN identifier of a VXLAN to which the target host device belongs. and in response to a determination that routing information of the target host device may be stored locally, the VTEP sends an address resolution response comprising a MAC address of the target host device to the source host device.

摘要： Via a tunnel configured on a Virtual eXtensible Local Area Network (VXLAN) Tunnel End Point (VTEP), a notification message is received from a peer VTEP over the tunnel. The received notification message contains VXLAN Network Identifiers (VNIs) of VXLANs currently configured on the peer VTEP. For each of VXLANs currently configured on the VTEP, when the same VXLAN as the VXLAN configured on the VTEP exists in the VXLANs indicated by the VNIs contained in the received notification message and when the VXLAN configured on the VTEP has not been associated with the tunnel, the VXLAN configured on the VTEP is associated with the tunnel.

摘要： According to an example, in an AC pool including a MAC and a plurality of LACs registered on the MAC, after a first LAC is registered on the MAC, the MAC issues a first traffic rule to the first LAC, wherein the first traffic rule redirects a discovery packet sent from an AP to the MAC. When receiving the discovery packet sent from the AP or receiving a discovery packet sent from the AP and forwarded via a LAC, the MAC selects, from a plurality of the LACs, a second LAC for handling the AP. The MAC generates a second traffic rule associated with the AP and the second LAC, and issue the second traffic rule to a plurality of the LACs, so that when another LAC receives a communication tunnel protocol packet sent from the AP, the other LAC redirects the communication tunnel protocol packet to the second LAC.

摘要： A method for setting software defined network (SDN) flow entries. A packet transmitted from a host is received, and a local flow table of the SDN switch for a flow entry that matches address information of the packet is searched. In response to determining that the packet matches a default flow entry in the local flow table, the packet is transmitted to a SDN controller according to the default flow entry. A first flow entry in the local flow table is set according to a source address, a destination address and an input port of the packet. A priority of the first flow entry is higher than a priority of the default flow entry. An action of the first flow entry is a non-forwarding action.

摘要： The present disclosure describes reducing flooding of link state information of a link state protocol in a network with multiple routers. A filtering strategy is pre-configured on a router interface for filtering link state information generated by a first router. The filtering strategy is to enable link state database (LSDB) isolation between a second router associated with the router interface and the first router. Link state information generated by the first router is received or sent according to the pre-configured filtering strategy via the router interface.

摘要： Searching, according to the type information of a network device, for a transport layer protocol supported by the network device in a transport layer architecture of a network configuration protocol (NETCONF) configuration framework and definition information which is to be used to implement a connection to the network device. Establishing a NETCONF session to the network device by using the transport layer protocol and the definition information. During establishment of the NETCONF session, comparing a first NETCONF capability set obtained from the network device with a second NETCONF capability set which is supported by the NMS and is defined in a metadata definition file. Assigning an intersection of the first NETCONF capability set and the second NETCONF capability set as an active capability set. Then, performing a network configuration access to the network device based on the active capability set.

摘要： In an example, multi-protocol label switching traffic engineering (MPLS TE) fast reroute (FRR) is implemented in an MPLS TE network. The MPLS TE network includes a bypass protection (BP)-label switching path (LSP) protecting a working LSP. A node receives a packet from an upstream adjacent node of the node in a working LSP. The packet includes a label which is an incoming label of the working LSP at the node. When detecting a downstream adjacent node of the node in the working LSP is unreachable, the node replaces the label in the packet with an outgoing label of a WP-LSP at the node, and forwards the packet in the WP-LSP which delivers the packet to an ingress node of a BP-LSP. The BP-LSP then delivers the packet to an egress node of the BP-LSP and the packet is forwarded from the BP-SLP to the working LSP.
