Routing Policy Specification Language (RPSL) allows global routing policy to be in a single distributed database. Despite its name, RPSL is not a router configuration language. RPSL is oriented toward objects, which contain policy and administrative information that is registered in Internet Routing Registries (IRRs).

Overview[edit | edit source]

RFC 2622 explains that RPSL allows network operators to specify routing policies at various levels in the Internet hierarchy with enough detail that low-level router configurations can be generated. RPSL is extensible, meaning new protocols and features can be introduced at any time. RPSL replaces RIPE-181 (RFC 1786), which replaced RIPE-81 in October 1994.[1]

RPSL, which is case insensitive, describes aspects of routing policy, such as prefixes, Autonomous System Numbers, relationships between BGP peers, management responsibilities.[2]

Other RPSL specifications[edit | edit source]
