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.

Global services such as local load tuning and load balancing of the LeaderAP are limited by the performance of the AP, and the specifications of the APs that can be managed by theLeaderAP are limited

If the specifications are exceeded, if APs are not grouped, APs will be randomly grouped, and adjacent APs and APs on the same floor may be assigned to different groups, which will affect global services such as tuning and load balancing

AP groups in the current version are grouped through AP management VLANs, and APs in the same group need to have the same management VLANs

The AP tuning group division will be reflected on the controller of the current version

Support 2G large cache to cope with high burst business traffic.

It can be used as a remote module for the central switch to achieve simplified networking.

It supports advanced features such as VxLAN and MPLS, real-time telemetry data collection, and network O&M visualization, which can be widely used in scenarios such as medium-sized campus aggregation and small campus cores.

3 power supply design, support N+1 redundancy, full 802.3bt90W PoE++ power supply for all ports, and the maximum PoE output power of the whole machine can reach 2268W, adapting to the power supply needs of massive terminals.

Different EDGE devices choose different main outlets

Different upstream network segments choose different main exits

O&M capability: support restart operations on distributed switches: support reporting alarms for failed upgrade of distributed switches. Control capability: Configurations can be directly delivered to distributed switches (remote modules).

Control capability: support direct configuration delivery to distributed switches (remote modules).

Management capability: You can view the information of the distributed switch based on the central switch, including the ESN, model, online status, interface directly connected to the central switch, and the port list information of the distributed switch itself.

Monitoring capability: You can view the memory usage, storage space usage, and temperature of distributed switches, as well as the running status, rate, flow rate, packet statistics, and bandwidth utilization of distributed switch ports.

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.

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).

For L3VPN scenarios, you need to search in the VPNFIB of the egress PE

When the authentication point and the group policy execution point are not on the same device, you need to use the policy linkage function.

In the policy linkage scenario, you need to set the downstream port type of the Edge device to Extended Access Switch

The policy linkage function means that no matter where you go, the permission to access resources is the same, and it is decoupled from the IP address.

When the authentication point, access point, and group policy execution point are all connected to the device, the policy linkage function should be used

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.

and MAC address routes are filled with two labels (that is, both mplslable1 and mplslable2 are valid in packets).

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

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 toensure 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

The maximum number of XSIC slots can reach 4.

The maximum number of WSIC slots can reach 4.

4 SIC slots.

Dual master control and double forwarding

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.

For the Locator CIDR block planning of SRv6, the appropriate mask should be set according to the number of IPv6 SIDs that may be used by the device.

loatos svV6_locator ipu6-prelix21.DB8ABCD: .b4 static 32, Locator is 2001.DB8.ABCD:, length 64 bits, static segment occupies 32 bits, dynamic segment occupies 32 bits args field occupies O bits. The starting value of the state segment is: 2001:DB8:ABCD:0000:0000:0000:C

Locator SID supports static configuration or dynamic allocation, end-op and end-m must be statically configured, and static configuration is also recommended for end and end.x, which is convenient for network O&M. Other SIDs can be assigned dynamically.

Devices at the same site belong to the same large network segment with the same prefix, and different devices are assigned to the small network segment with the same prefix in the large network segment.
