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.

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

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

SIDs can be used anywhere in the segment list

CHECK THE PRIVATE FIB OF V4 ACCORDING TO THE INNER IPV4DA

You can use the destination address of IPV6 packets without SRH headers

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

and the two upstream traffic paths of the edge form ECMP load balancing

Different source CIDR blocks choose different main exits

Different EDGE devices choose different main outlets

Different upstream network segments choose different main exits

It is recommended to deploy two-way tunnels to pass through the common road, which is convenient for maintenance and more reliable tunnel BFD detection

When optimizing and calculating routes, priority is given to ensuring the creation of high-priority tunnels, and high-priority tunnels can preempt low-priority tunnel resources

RSVP-TE, SR-TE, and LDP tunnels can be tuned

When multiple load-balancing tunnels are deployed between two PE nodes, we recommend that you deploy a detached group.

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

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.

The static Opcode needs to be configured within the static segment range to prevent conflicts with the Opcode dynamically allocated by the IGP protocol. The static segment length range is determined by the static static-length parameter of the locator command.

end-op, and end-m need to be statically configured

end, end-x, end-dt4, end-dt6, and end-dx2 can be dynamically assigned or statically configured

The SRv6SID format is Locator:Function:Args, where the Args field is also called Opcode

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.
