General information about Selectel Global Router service
Infrastructure in regions Tashkent, Almaty and Nairobi cannot be interconnected with other regions using a global router, only intra-regional interconnection is available.
The Global Router allows the infrastructure in Selectel to be interconnected by a private network at the L3 level.
Through a global router, you can merge:
- different products and services: Dedicated servers, Equipment placement, A-DC, Cloud platform (Cloud servers, Managed Kubernetes, Cloud databases), VMware-based cloud, Fault-tolerant load balancer, File storage;
- servers in different poolahs: dedicated servers, hosted servers, cloud servers, Managed Kubernetes nodes;
- private networks of different accounts.
For smooth operation, all equipment used for the service is booked on an N+1 basis.
The service supports user types and roles.
Principle of operation
A global router routes traffic between private subnets connected to it, providing L3-level network connectivity between different services and different pools.
The role of the global router is performed by a separate routing table located on multiple physical routers. For this purpose, in each pool a separate physical router is allocated and reserved that serves only the global router networks. These physical routers are aggregated into a single IP/MPLS routing domain.
Network fault tolerance is provided by equipment redundancy, dynamic routing protocols, and routing redundancy in the network. The operability of the entire network does not depend on the operability of a single segment. For example, if communication with one of the pools fails, the rest of the network will continue to operate.
Example of connecting networks to a global router:
The details and benefits of organizing network connectivity at the L3 level are described in the blog article Consolidation of projects in different data centers.
Limits
The account has limits on the number of routers and networks and subnets on a single router. To change the limits file a ticket.
- 5 global routers (5 independent private routed networks);
- up to 50 networks in each global router;
- Up to 50 private subnets (IP subnets) in one network;
- up to 50 static routes for a global router;
- all networks connected to the same router must not have overlapping subnets (the available IP addresses of each subnet must not overlap with the IP addresses of other subnets).
Cost
Selectel Global Router is free of charge if:
- infrastructure is integrated within one regions;
- or a bandwidth of no more than 1 Gbps is used between regions.
If you are already using a larger lane, we will contact you in the ticket and negotiate customized terms.
