In the SDN-WAN solution, the principles that need to be followed in the design of ISIS Cost are incorrectly described ()

The link cost between the RR and the PE is extra-large, and it is recommended to set 10,000 to ensure that the RR device is only responsible for control plane route reflection and does not forward traffic

The COST configuration of the MSTP link of the remote operator is larger, and it is recommended to configure 1000 to avoid traffic bypassing through the WAN link - the test is wrong

The COST configuration of the link of WDM or bare fiber in the same city is the second smallest, and it is recommended to configure 200 to ensure that the route calculation is secondary to the same city link

The COST value of the local link is the smallest, and it is recommended to configure 10 to ensure that the route calculation gives priority to the local link test error

The link cost between the RR and the PE is extra-large, and it is recommended to set 10,000 to ensure that the RR device is only responsible for control plane route reflection and does not forward traffic

When doing BGP design in SDN-WAN, it is recommended to divide devices with the same configuration into the same group to simplify configuration and maintenance.

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).

IN QOS DESIGN, THE DESCRIPTION OF THE DESIGN PRINCIPLES OF TRAFFIC SCHEDULING IS INCORRECT ()

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

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

Regarding the description of tunnel planning, it is incorrect ()

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.

SRv6 Policy Group tunnel planning description, incorrect is ()

The minimum color of the SRv6 Policy Group tunnel group is 1,000,000, and the colors of different VPN services and planes do not need to be distinguished, but can be the same.

Establish an SRv6 Policy Group tunnel group for local and remote devices on the same plane.

The minimum color of the SRv6 Policy Group tunnel group is 1,000,000, and the colors of different VPN services and planes do not need to be distinguished, but can be the same.

Configure an SRv6 Policy Group tunnel group for a VPN service.

Multiple policy tunnels can be planned within the group according to the actual needs of users.

In the government unified construction mode of SDN-WAN solution, the SRv6 tunnel design description is incorrect ()

Service slices must use SRv6 Policy tunnels, which can be strictly explicit or loose.

The whole network uses NCE-P to calculate the path of the slice network based on the affinity attribute to ensure the optimal path of the whole network and make full use of the link bandwidth while ensuring the service quality.

SRv6Policy tunnels are vertically deployed between districts, counties, cities, and provincial WANs to optimize traffic to improve bandwidth utilization and ensure service quality.

SRO6fPolicy tunnels can be carried in the default slice network or in a non-default slice network. For default slices, SRv6BE is preferred. Services with special requirements can also be carried through SRv6 policy tunnels.

In the government affairs scenario of the SDN-WAN solution, the design description of the service VPN access network slicing solution is incorrect ()

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

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.

The following statements about MAC routing are incorrect ()

The Route Distinguisher value (RD value) of the MAC route is generated by the value configured by the evpn source-address

If the Flag value of the migration attribute in the MAC address route is 1, it indicates a static MAC address, and the static MAC address is preferred.

When a MAC address route is migrated, the large sequence number in the MAC migration attribute is preferred.
