Kevin Myers talks at the Mikrotik conference about the use of BGP & OSPF in WISP design. WISP networks are quite different from your garden variety Enterprise IT WAN because the architecture is driven by where you can place your poles & antenna shots. This most often results in loops, path asymmetry and sub-rate bandwidth.
WISP Design: Using eBGP and OSPF transit fabric for traffic engineering, Kevin Myers – iparchitechs.com (IP ArchiTechs, USA). In this presentation on WISP network design, we will look at using an OSPF transit fabric for unequal load balancing between towers and eBGP with communities as a way to influence traffic throughout the entire WISP.
Kevin is a big of Mikrotik routers and whitebox switches running Cumulus. Its a refreshing take on how to do things differently and some really good ideas.
Students of networking should also find this stimulating because it challenges your understanding of the basics of OSPF, BGP and why you use them.
