Huawei comprehensive network topology experiment, combined with some basic configurations of Huawei routers and switches and link aggregation of Huawei equipment.

# what is link aggregation? Link aggregation bundles multiple physical links into a single logical link; enhances transmission data bandwidth and throughput; link aggregation members fail over automatically to forward data on other links; link aggregation distributes traffic to different member links to forward data to reduce congestion; # what is the purpose of link aggregation? Speed up transmission speed and provide network load balancing; link aggregation of Huawei devices is equivalent to Ethernet channels of Cisco network devices; # Mode of link aggregation? 1) Manual mode is referred to as manual load sharing mode; all ports in manual mode participate in data forwarding and traffic sharing; port administrators participating in link-state aggregation are added manually; manual mode link-state aggregation does not send LACP link-state aggregation protocol, only manual load sharing is supported; load balancing at source-destination MAC and IP addresses is supported 2) all devices running link-state aggregation in static LACP mode send LACP protocol to negotiate link aggregation parameters; run LACP negotiation to elect active and inactive ports; static LACP mode is also known as MRV N mode; M represents active member link, N represents passive link redundant backup traffic; active member link failure automatically switches over to high priority inactive link to forward data 3) the difference between manual mode and static LACP mode. In manual load mode, all ports are in forwarding state; in static LACP mode, some ports are in forwarding state and some are in backup state; # load balancing mode? Dst-ip (destination IP address) mode: load sharing based on destination IP address; dst-mac (destination MAC address) mode: load sharing based on destination MAC address; src-ip (source IP address) mode: load sharing based on source IP address; src-mac (source MAC address) mode: load sharing based on source MAC address Src-dst-ip (XOR between source IP address and destination IP address) mode: load sharing is based on source destination IP address; src-dst-mac (XOR between source MAC address and destination MAC address) mode: load sharing based on source destination MAC address

Considerations for link aggregation to join members

Each Eth-Trunk interface can contain up to 8 member interfaces; member interfaces cannot be configured with any functions and static MAC addresses separately; when member interfaces join Eth-Trunk, they must be the default hybrid type interface (this type is the default interface type for Huawei devices); Eth-Trunk interfaces cannot be nested, that is, member interfaces cannot be Eth-Trunk An Ethernet interface can only join one Eth-Trunk interface, and if you need to join other Eth-Trunk interfaces, you must first exit the original Eth-Trunk interface; the member interfaces in an Eth-Trunk interface must be of the same type, that is, Fee port and GE port cannot join the same Eth-Trunk interface; Ethernet interfaces on different interface boards can be added to the same Eth-Trunk If the local device uses Eth-Trunk, the peer interface directly connected to the member interface must also be bundled into an Eth-Trunk interface so that the two sides can communicate normally; when the rate of the member interface is inconsistent, the interface with low speed in use may become congested, resulting in packet loss; when the member interface joins the Eth-Trunk, the MAC address is learned according to Eth-Trunk, not according to the member interface

The topology diagram of Huawei network equipment is as follows

The configuration steps are as follows: PC configures IP address and gateway SW1 and SW2 according to topology, link aggregation and trunk creates vlan10, vlan20 and vlan30 in SW1 and SW2, respectively, adds interface to vlanR1 and configures single-arm routing, communication between different vlan R1 G0Unipoise 1 interface configures IP address and R2 interface configures IP address PC7 configures IP address and gateway R2 configures default route, R1 configures static route, PC7 can access all vlan Network-wide interconnection R1 and R2 configure floating route PC7 verify floating route network-wide interconnection
