Demand for networking

Such asfigure 1It shows that the IP network can meet the M-lag dual-return IP network:

• When a connection link fails, the traffic can be quickly switched to another link to ensure reliability.

• In order to efficiently use bandwidth, the two links are in the Active state at the same time, and the traffic can be used to use load sharing.

Configuration

Use the following ideas to configure the M-LAG dual-return access IP network:

1. Configure the uplink interface on Switch to an ETH-TRUNK.
2. Configure V-Stp, DFS Group, Peer-Link, and M-Lg interfaces on Switcha and Switchb.
3. The VLANIF interface IP address and MAC address are configured on Switcha and Switchb as the dual -live gateway to access the device.
4. The OSPF features are configured on Switcha, Switchb and SwitchC to ensure the three layers of interoperability.
5. Configure the Monitor Link associated upward interface and downlink interface on Switcha and Switchb to avoid being discarded by user side traffic due to uplink chain failure.

Steps

1. Configure the upper interface on Switch to be bound in an Eth-Trunk

1. Configure the VLANIF interface IP address and MAC address on Switcha and Switchb respectively as the dual -live gateway to access the device

The IP and virtual Mac configuration at both ends requires exactly the same, the purpose is to provide the same IP and virtual Macs for M-Lg.

，“Heart beat state” “OK”， ；SwitchA Node 1， 150，“State” “Master”；SwitchB Node 2， The priority is 120, and the state of "State" is "backup". At the same time, the status of "causion" is "-", Node 1's "port state" state is "up", Node 2's "port state" state is "up", and the M-lag status of Node 1 and Node 2 is both in the state of Node 1 and Node 2 are both. "Active" indicates that the configuration of M-Lg is correct.
