While we make every effort to ensure the accuracy of Spokes maps, no map can ever be guaranteed free of errors. We would be grateful if you would let us know about any mistakes you spot, so that they can be corrected in the next edition. Please email spokes@spokes.org.uk.

As all packets go across the hub, almost any dynamic routing protocol would help with attaining reachability. The hub just needs to advertise a default route to spokes, while spokes should advertise their subnets dynamically to the hub. Probably it makes sense to run EIGRP and summarize all subnets to 0.0.0.0/0 on the hub, effectively sending a default route to all spokes (if the spokes do not use any other default route, e.g. from their ISPs). Configure spokes as EIGRP stubs and advertise their respective connected networks. RIP could be set up in a similar manner, by simply configuring GRE tunnels on spokes as passive interfaces. Both EIGRP and RIP require split-horizon disabled on the hub mGRE interface in order to exchange subnets spoke to spoke. As for OSPF, the optimal choice would be using point-to-multipoint network type on all GRE and mGRE interfaces. In addition to that, configure ip ospf database filter-all out on the hub and set up static default routes via tunnel interfaces on the spokes (or static specific routes for corporate networks).

We see how NRHP Phase 1 works now. The spokes register their associations with the hub via NHRP and the hub learns their NBMA addresses dynamically. At the same time, spokes use point-to-point tunnels to speak to the hub and reach each other. Note that EIGRP is not the only protocol suitable for use with NHRP Phase 1. OSPF is also a viable solution, thanks to point-to-multipoint network type and database filter-all out command. See the example below for OSPF configuration with NHRP Phase 1:

First, the hub needs to know how to authenticate all the spokes using IKE. The most scalable way is to use X.509 certificates and PKI, but for simplicity, we will just use the same pre-shared key on all routers. Note that we need to configure the routers with a wild-card pre-shared key, in order to accept IKE negotiation requests from any other dynamic peer.

Macro layout has been investigated in a number of studies, in which the entire network is mapped using different design rules, e.g., octolinear versus curvilinear [BD84, RNL*13, RV16], octolinear versus curvilinear versus multilinear [RGL17] and octolinear versus concentric circles and spokes [RNC16]. There can be difficulties in interpreting such studies, although the question of which design rules result in the most effective designs generally, or for specific networks, is an important one.

Most of the 12 major U.S. passenger airlines in operation as of 2001 use a hub-and-spoke network to route their plane traffic. The words "hub" and "spoke" create a pretty vivid image of how this system works. A hub is a central airport that flights are routed through, and spokes are the routes that planes take out of the hub airport. Most major airlines have multiple hubs. They claim that hubs allow them to offer more flights for passengers. ff782bc1db
