ABSTRACT:
Wide-area data communications utilize regional networks transporting IP-over-Ethernet on fiber. For certain Layer 2 services, a regional implementation of the network makes limited use of spanning tree protocol on a backbone ring. Learning bridge operations in switches on associated access rings involve a short default for an aging timer. For use of Open Shortest Path First (OSPF), the connection of each access ring to the backbone ring uses a pair of routers with dual links therebetween. One of these links is bonded to the backbone (OSPF Area0), whereas the other link is bonded to the Area of the respective access ring. Also, certain routers within each regional network form a mini-autonomous system, for boundary gateway protocol (BGP). The mini-autonomous systems of the regional networks form a confederation. The network utilizes route reflectors in the mini-autonomous systems. The Internet carries confederation commands to and from a designated hub.
