VPP: A 1Tbps+ router with a single IPv4 address (denog16)

Chaos Computer Club - recent events feed

In this talk, we explore the changes needed to convert a set of fully open source amd64 based VPP routers running in AS8298 to be able to use exactly one IPv4 and IPv6 address in an OSPFv3 and iBGP configuration. The use of /30 or /31 IPv4 transit networks between routers is a thing of the past, paving the way to conserve IPv4 addresses! The talk discusses the changes made to VPP and a popular routing suite Bird2, to enable both Babel and OSPFv3 to route traffic without using IPv4 transit networks, including operational notes how the author rolled this out in AS8298. Finally, the author will make good on his promise from previous DENOG, predicting a 1Tbps VPP machine.
