Through this tool, you can restore the user's existing network networking and service characteristics

It is mainly used to generate configuration scripts in batches

It is mainly used to specify the relocation plan and design the networking structure of the new network

The above statements are correct

The number of APs is greater than 50 or equal to 0

The number of APs is greater than 100 or equal to 0

When the signal strength in the floor is too low

In the case of insulating obstacles

The RR must be redundant, and at least two RR devices must exist on the live network. Prevent network-wide service interruption caused by the failure of only one RR device on the entire network.

Try to choose an independent RR, which can be deployed on a single device in the independent RR scenario.

Use the RR model recommended in the specification list;

The Edge should be dual-uplink to the two RR devices to achieve egress backup;

Deploy a VRF instance for each slice

Each VRF instance is configured with a routing policy to color a specific color

After the SRv6Policy tunnel in the slice matches the color, the VRF instance is iterated to the SRv6Policy tunnel in the corresponding slice after the head node matches the color.

FLEX-E technology is recommended for interfaces below 50GE and channelized interface technology for interfaces of 50GE and above.

All backbones P(P) 1 group

1 GROUP OF PE (BR-PE) in all branches

1 GROUP OF PE (DC-PE) for all data centers

1 group for all RR devices (RR).

Maintain the principle of uniformity in the scheduling strategy of the whole network, and use templated deployment as much as possible to facilitate network management

LPQ/WFQ scheduling strategies can be used to avoid low-priority services not being able to obtain bandwidth resources

The current QoS policy needs to take into account the subsequent expansion of the network

Core services and video-voice services should ensure the absolute priority of forwarding and use PQ scheduling

Unless the business has special requirements, some parameters of the scheduling policy should be defaulted as much as possible

For TCP-based services, the queue must be configured with WRED dropping to avoid TCP global synchronization

AC side-attached data is forwarded directly

AC side-attached data tunnel forwarding

Layer 3 networking data is forwarded directly

Layer 2 networking data is forwarded directly

Coverage areAnswer: confirm the key coverage area (such as office, conference room, etc.) and common coverage area (such as stairs, toilets, etc.) required by the customer

Pay the signal field strength requirements in the area, for example, -40dBm~-65dBm in key areas, and > -75dBm in ordinary areas

Number of concurrent users: the total number of terminals connected in the current coverage area, and how many people in the coverage area are planned to be connected at the same time

Bandwidth requirements: the main types of services planned by the customer and the bandwidth requirements for each user

RA packets can carry a lot of network configuration information, including the default router, network prefix list, and whether to use a DHCPv6 server for stateful address allocation. An attacker can send forged RA packets to modify the network configuration of the user's host so that legitimate users cannot communicate properly. IPv6RGuard provides a defense mechanism against RA packet attacks, which can effectively prevent such network at

Configure the host or router role for the interface, and then the device can forward or discard RA packets based on the interface role.

If the interface is connected to the user host, the interface role is set to host, and if the interface is connected to the router, the administrator can configure the interface role to router according to the interface networking. Version 22.0 also supports policy-based filtering of ND packets.

22.0 also supports policy-based filtering of ND packets.

SRv6 Policy Group, SRv6 Policy, and SRv6-BE tunnels are delivered and deployed through the iMaster NCE-IP.

VPN services in the backbone network can be carried by SRv6 Policy Group, SRv6 Policy, and SRv6-BE tunnels.

For L2EVPN services, SRv6Policy tunnels are used first, followed by SRv6-BE for escape.

For L3EVPN services, it is recommended to use SRr6Policy Group tunnels for DSCP traffic diversion and SRv6-BE tunnels for escape if the SRv6 Policy tunnel fails to iterate routes.

If you already have a tool, you can fully trust the tool, and you don't need special skills

I have a relatively high education, and I can solve problems by myself and can use them

The tool is simple, and I have two years of work experience, so there is no problem with it

Have systematic and professional knowledge of data communication network, and have more than two years of experience in data communication equipment development and maintenance
