FORWARDING A PACKET BY A NVE IN NVO3 NETWORK

摘要

A method for forwarding a packet by a first Network Virtualization Edge (NVE) in Network Virtualization Overlays, Layer 3 (NVO3) and an NVE is provided. The method comprises, in response to receiving an IP packet from a first Virtual Access Point (VAP) of the first NVE, looking up forwarding information to obtain an IP address of a second NVE; in response to lookup fails, or the IP address of the second NVE being different from an IP address of the first NVE or the second VAP being different from the first VAP, dropping the IP packet; and in response to the IP address of the second NVE being the same as an IP address of the first NVE and the second VAP being the same as the first VAP, forwarding the IP packet.

1. A method for forwarding a packet by a first Network Virtualization Edge (NVE) in Network Virtualization Overlays, Layer 3 (NVO3), the method comprising:
in response to receiving an IP packet from a first Virtual Access Point (VAP) of the first NVE, looking up forwarding information by taking a source IP address of the IP packet as an IP address of a first Tenant System (TS) and by taking a first Virtual Network Identifier (VNID) to which the IP packet belongs as a VNID to which the first TS belongs, to obtain an IP address of a second NVE to which the first TS is connected and a second VAP to which the first TS is connected; in response to at least one lookup fail, or the IP address of the second NVE being different from an IP address of the first NVE, or the second VAP being different from the first VAP, dropping the IP packet; and in response to the IP address of the second NVE being the same as an IP address of the first NVE and the second VAP being the same as the first VAP, forwarding the IP packet by using a destination IP address of the IP packet.
