Private Routed Networks

Glossary

Term Definition
Region Data center locations
Location A technical site within one region logically united by a single policy for passing local and Internet traffic with a unique set of racks, servers, and network devices.
Layer 2 connectivity is established within a location to provide the local network service. This service uses separate network devices located in the same set of racks
Resource type - Dedicated Servers
- Cloud Platform
- Cloud powered by VMware
- Colocation
- Port to a third party operator
- Direct Connect

Resource type is the final host in the products between which we create local connectivity. The resource in the product must have a local port connected
Network devices Network devices include switches, routers, and firewalls, virtualization tools located within each location that are used for connecting the servers.
Within one location, the Internet and the local network are completely isolated from each other. Network devices of the local network do not have logical or physical connection with the network devices on the Internet
Host A dedicated or virtual server or other network interface (for Direct Сonnect services, Port to a third party operator, Firewall port, and so on) on the network that has one or several IP addresses and is connected to the network devices of the location
Private network segment A part of the client’s local infrastructure belonging to the same resource type, located in one location and having a single VLAN ID
You can create up to 10 network segments in total for all resource types
VLAN (network, private network) Unique networks isolated from each other at the Layer 2, created on the network devices of the location for delimitation of client network segments.
VLANs (networks, private networks) are created in the location for the local network, which is created on network devices
Private IP address IP address that can be assigned to access a specific host on a private network segment for providing connection with other hosts
Subnets (IP addresses) The range of private IP addresses limited by the size of a prefix (mask) provided by the client. It is allowed to use the range of IP addresses described in RFC 1918, namely: 10.0.0.0/24, 172.16.0.0/12, 192.168.0.0/16.
The minimum subnet size is /29.
Each network segment must use a unique range of IP addresses. The same addressing cannot be used in different segments for the private network.
You can assign multiple subnets of any size larger than the minimum subnet size to one VLAN (network) in each segment.
You can create up to 10 private subnets (IP subnets) in each segment
Termination Assigning a private IP address of one or more client subnets to the specified VLAN (network) on the virtual router interface.
Once assigned, this IP address can be used as the default gateway of the subnet to which it belongs.
Termination allows you to get routed (Layer 3) connectivity with other subnets of the private network
Static routing Directs traffic from the private network to the destination subnet (external for this network) through the internal IP address (next hop).
A static route can only be created if there is at least one segment in the private network.
When setting a static route, the following parameters are specified:
- destination subnet address (to which traffic is routed);
- subnet mask;
- gateway address (host, next-hop) that facilitates further routing
VRRP (Virtual Router Redundancy Protocol) is a networking protocol that increases the availability of routers serving as the default gateway.
It is used as a standard connection. To enable VRRP, the client needs to allocate two IP addresses from each used subnet (in addition to the default gateway address)
Virtual IP address (VIP address) A virtual IP address on the router used by the host as a default gateway or as a next-hop by the static routes
Virtual router Combines network segments in several regions, locations between selected resource types into a distributed private routable network at Layer 3.
You can create 5 virtual routers per account, which allows you to create up to 5 independent private routed networks.
Each virtual router can create up to 10 network segments.
Each network segment can create up to 10 private subnets (IP subnets).
You can set up to 10 static routes for a virtual router.
Please create a ticket to change the limits.

Establishing Connectivity between the Selected Resource Types in Different Locations

Please note that this functionality can be used to connect the same resource types in different locations. For example, between dedicated servers located in different locations.

A private routed network based on Layer 3 switching is used to establish network connectivity between different locations and resource types.

Connecting the Service

To connect the service, fill in the form and submit a request on the Private Networks tab of the Network Services section in the Control panel:

  1. Specify which addressing will be used in each location.
  2. Specify which IP addresses will be used as gateways (3 in each location).
  3. Specify the static routes, if necessary.

Сonnecting Network Segments to a Virtual Router

One virtual router is a combination of several physical routers. All equipment required to provide the Routed Private Networks service has N+1 redundancy to ensure uninterrupted operation.
