RPKI ASPA: a complement to RPKI/ROA that tackles BGP route hijacks through AS path manipulation.
The IPv4 full BGP table size is around 725000 prefixes now. This may cause problems for companies that do not have the resources to update or upgrade their edge routers.
But, except for Internet transit providers, who really need to get the full IPv4 BGP table today? And what are the alternatives?
Let’s see that in detail with some use cases.
On Cisco routers, by default the BGP protocol will not do load-sharing – and even less unequal cost load-sharing – across multiple links, for traffic to the same eBGP destination with different AS-path. Let’s see how we can change this.
