Blok CIDR Router transit adalah Blok CIDR kustom yang dapat Anda buat untuk Router transit. Blok CIDR ini mirip dengan Blok CIDR yang digunakan untuk menetapkan alamat IP ke antarmuka loopback router. Panggil operasi CreateTransitRouterCidr untuk membuat Blok CIDR untuk Router transit.
Deskripsi operasi
A transit router CIDR block is a custom CIDR block that you can create for a transit router. It is similar to a CIDR block used to assign an IP address to a router's loopback interface. A transit router CIDR block is used to allocate IP addresses to network instance connections. For more information, see Transit router CIDR blocks.
The CreateTransitRouterCidr operation is used to add a CIDR block to a transit router only after the transit router is created.
Before you create a transit router CIDR block, note the following information:
-
Only Enterprise Edition transit routers support CIDR blocks.
-
For more information about the limits on transit router CIDR blocks, see Limits on transit router CIDR blocks.
-
A transit router supports up to five CIDR blocks. The subnet mask of each CIDR block must be 16 to 24 bits in length.
-
You cannot create CIDR blocks that are within 100.64.0.0/10, 224.0.0.0/4, 127.0.0.0/8, or 169.254.0.0/16, or their subnets.
-
Each CIDR block must not conflict with the CIDR blocks of interconnected network instances in the Cloud Enterprise Network (CEN) instance.
-
Each CIDR block must be unique within the same CEN instance.
-
After you add a CIDR block to a transit router and create the first VPN connection on it, the system automatically allocates three CIDR blocks from the specified CIDR block. These three CIDR blocks are reserved by the system for creating VPN connections. The system then allocates IP addresses to IPsec connections from the remaining CIDR blocks.
You can call the ListTransitRouterCidrAllocation operation to query the CIDR blocks that are reserved by the system or allocated to IPsec connections.
