Routers

Routers are the packet-layer devices that form the backbone of the GÉANT network. They only require an active site subscription to be available, which is the location one is hosted at. Virtually all services depend on an active router subscription. As a result, this is one of the most fundamental subscription instances in GSO.

From a bird's-eye view, the process of deploying a new router in the network is as follows:

  1. Manually configure the router such that it is reachable from out-of-band (OOB).
  2. Upgrade the router to the most recent OS.
  3. Deploy base configuration.
  4. Configure trunks to connect the router to the network.
  5. Update the protocol meshes (such as iBGP).
  6. Promote the router to the production environment.

Provisioning a router in WFO

WFO provisions a new router by following the steps shown here.

Modelling and attributes

The attributes of a router are as follows:

Attribute name Attribute type Description
router_fqdn str The FQDN of a router
router_ts_port PortNumber The port of the terminal server that this router is connected to.
Used to offer out of band access.
router_access_via_ts bool Whether this router should be accessed through the terminal server, or through its loopback address.
router_lo_ipv4_address IPv4Address The IPv4 loopback address of a router.
router_lo_ipv6_address IPv6Address The IPv6 loopback address of a router.
router_lo_iso_address str The ISO address of the router, used for ISIS support.
router_role RouterRole The role of the router, which can be P, PE, or AMT.
router_site SiteBlock The site that this router is located at.
vendor RouterVendor The vendor of a router, either Juniper or Nokia.

Deployment

For the deployment of a router, two workflows are required to be run. The first is creation of the router subscription itself, and preparing it for insertion into the network. After completing this workflow, it needs to get added to the iBGP mesh of existing routers in the network.

Tip

The creation of a new router also requires an active site subscription, ensure that this is already in place before continuing.
