Networking Requirements
As shown in Figure 1-16, on an IPv6 network, data center customers require device isolation at the access layer, control plane isolation, and device fault isolation, packet forwarding in active-active mode without being affected by upgrade. Multichassis Link Aggregation Group (M-LAG) Lite decouples the control planes of multiple devices, and achieves packet active-active forwarding in active-active mode among the devices, without the need to configure heartbeat links to synchronize data through negotiation packets.
Configuration Roadmap
This example only explains the configuration of IPv6 M-LAG Lite. If you need to configure M-LAG Lite over the IPv4/IPv6 dual stack, see Example for Configuring M-LAG Lite and this example.
The configuration roadmap is as follows:
- Configure servers to connect to leaf switches in M-LAG Lite mode.
To ensure successful Eth-Trunk negotiation, ensure that Leaf1 and Leaf2 have the same LACP system priority and Eth-Trunks have the same interface ID and LACP system ID. In addition, the Eth-Trunk member interfaces on the two leaf switches must have different numbers in the LACP protocol to prevent LACP negotiation failures.
- Configure an IPv6 address for each interface.
- Configure the same IPv6 address and MAC address for VLANIF interfaces on leaf switches. The leaf switches function as the active-active gateways of servers.
- A leaf switch must be a Layer 3 gateway but not a Layer 2 transparent transmission device. If a spine switch serves as a Layer 3 gateway and servers connect to leaf switches in M-LAG Lite mode, server ND entries learned by the spine device will have two egresses and MAC address flapping occurs. Therefore, the leaf switch to which servers connect in M-LAG Lite mode must be a Layer 3 gateway.
- To make leaf switches function as Layer 3 gateways, that is, all traffic from servers to leaf switches be forwarded at Layer 3 (including the traffic forwarded in the same Layer 2 domain), enable proxy ND on leaf switches.
- Configure the same IPv6 addresses for gateways on Leaf 1 and Leaf2 so that ECMP load balancing is performed on the traffic from spine switches to leaf switches. If a link between a server and leaf switch fails, for example, a link between Server1 and Leaf1 becomes faulty, only one link is available for traffic transmission and the traffic from Server1 to Leaf1 may be interrupted due to hash-based ECMP. Therefore, you need to ensure that the gateway interface of a leaf switch can advertise the NDP Vlink direct route to its neighbors and advertise the host route translated by the ND to spine switches. Then you need to configure a corresponding dynamic routing protocol on leaf switches to import the direct route. If the preceding fault occurs, the ND entry mapping Server1 on Leaf1 is deleted, the NDP Vlink direct route is unavailable, and the traffic from spine switches to Server1 is forwarded to Leaf2 to ensure normal traffic forwarding.
- To ensure normal communication between Server1 and Server2, after learning the NDP Vlink direct route advertised by leaf switches, spine switches advertise the route to other leaf switches. In normal cases, both the host routes translated by the ND (not delivered to the forwarding entry) and the host routes advertised by spine switches are available on leaf switches. You need to set a higher priority for the host routes translated by the ND, to ensure that the local ND entries are forwarded. If a link between a server and leaf switch fails, for example, a link between Server1 and Leaf1 fails, the ND entry mapping Server1 on Leaf1 is deleted, and the NDP Vlink direct route becomes unavailable. The traffic from Server2 to Server1 starts from Server2, Leaf1, Spine1 or Spine2, Leaf2, and finally arrives at Server1.
- Configure a routing protocol between leaf and spine switches to establish neighbor relationships.
Associate uplink and downlink interfaces in the Monitor Link group on the leaf switch to prevent user-side traffic from being discarded due to uplink faults.
Procedure
- Configure inter-device link aggregation in LACP mode.
