WISP Design – OSPF “Leapfrog” path for traffic engineering
Introduction
One challenge that every WISP owner or operator has faced is how to leverage unused bandwidth on a backup path to generate more revenue.
For networks that have migrated to MPLS and BGP, this is an easier problem to solve as there are tools that can be used in those protocols like communities or MPLS TE to help manage traffic and set policy.
However, many WISPs rely solely on OSPF and cost adjustment to attempt to influence traffic. Alternatively, trying to use policy routing can lead to a design that doesn’t failover or scale well.
Creating a bottleneck on a single path
WISPs that are OSPF routed will often have a primary path back to the Internet at one or more points in the network typically from a tower that aggregates multiple backhauls.
As more towers are added that rely on this path, it can create a bottleneck while other paths are unused.
Creating an alternate best path by leapfrogging another router
One way to solve this problem is to use VLANs to create another subnet for OSPF to form an adjacency.
By tagging the VLAN from Tower 6 through Tower 3 and into Tower 4, a new path Continue reading
