How Do I Add a Route?

After creating a Selectel global router (formerly L3VPN), the client needs to configure routing between network segments by registering routes to each segment of the used network through new gateway addresses.

For such a network:

  1. Segment machines must be connected to the dedicated networks.
  2. IP addresses on the interfaces must be configured.
  3. Segment 1 requires a route to network a.a.a.a via GW (b.b.b.254).
  4. Segment 2 requires a route to network b.b.b.b via GW (a.a.a.254).

For Windows

route -p ADD a.a.a.a MASK 255.255.255.0 b.b.b.254 METRIC 1

, where:

  • route is a program for working with routes;
  • ADD is a command to add a route;
  • -p key is needed to save the route;
  • MASK is a network mask;
  • METRIC 1 is a parameter defining the priority of the above gateway, where 1 is the highest priority.

You can check the added routes using the route print command.

For Linux

route add -net a.a.a.a netmask 255.255.255.0 gateway eth0

For CentOS

route add -net a.a.a.a/24 gw b.b.b.254
