Abstract

The invention discloses realization method and device of an MCE (Media Center Edition) agent function. The realization method of the MCE agent function is applied to a process that a single board inside switch equipment, which supports an MCE function, agents a single board which does not support the MCE function to realize the MCE function. The single board which does not support the MCE function is provided with an ACL (Access Control List), and the ACL corresponds to a router port of the single board and is used for indicating that a message is transmitted to a designated port of the single board which supports the MCE function; and the single board which supports the MCE function is provided with the mapping relationship between the router port information of the single board which does not support the MCE function and VRF (Virtual Routing Forwarding Table). The method comprises the following steps of: after the router port of the single board which does not support the MCE function receives the message, transmitting the message by using the router port as a message source port according to the corresponding ACL; after the designated port of the single board which supports the MCE function receives the message, acquiring the source port information of the message and the corresponding VRF according to the mapping relationship, and transmitting the message according to the VRF.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a method and a device for realizing an MCE agent function. Background technique

[0002] With the continuous refinement of user services and the improvement of security requirements, users in a private network need to be divided into multiple VPNs (Virtual Private Network, virtual private network) in many cases, and services between different VPN users need to be completely isolated. At this time, configuring a single CE (client device) for each VPN will increase the user's equipment expenses and maintenance costs; while multiple VPNs share one CE and use the same routing table entry, data security cannot be guaranteed sex.

[0003] Using the MCE (Multi-VPN-Instance CE, multi-instance CE) function provided by the Ethernet switch, multiple users can share one CE, which can effectively solve the contradiction between user data security and network costs brought about by mul...

Embodiment Construction

[0028] Since the routing port of the switch board does not have the corresponding function of VLAN, it is impossible to send the ACL matching the VLAN ID to the routing port of the board, so that the VLAN traffic corresponding to the VLAN ID sent to the board All are redirected to the proxy board through the ACL of the routing port to realize the MCE proxy function.

[0029] Aiming at the problem that the MCE proxy function of the routing port cannot be realized on the existing switch equipment, the embodiment of the present invention provides a technical solution for realizing the MCE proxy function on the routing port of the switch. In this technical solution, for the single board that does not support the MCE function, a routing port MAC (MediaAccess Control, Media Access Control) address and its corresponding ACL are set at its routing port. The ACL corresponding to the MAC address of the routing port redirects the message to the proxy board, and the proxy board uses the p...
