BGP - Border Gateway Protocol
A BGP is a session-based routing protocol defined within RFC4271 that is characterized by high levels of stability and scalability. Autonomous systems (AS) are connected via BGPs.
IGP - Interior Gateway Protocol
IGP is the name given to routing protocols that guarantee the accessibility of individual networks within an autonomous system (AS).
MPLS - Multiprotocol Label Switching
MPLS (RFC3031) refers to pre-signaled paths within an autonomous system (AS) that can be used for different services.
First Hop Redundancy Protocol - First Hop Redundancy Protocol
First Hop Redundancy Protocols provide a virtual IP address that is taken over by a backup router in the event of an error, thus guaranteeing connectivity. Examples for First Hop Redundancy Protocols include HSRP, VRRP, and CARP.
RIPE / RIPE NCC
The Réseaux IP Européens Network Coordination Center is Europe’s Regional Internet Registry (RIR). RIPE is the association of European Local Internet Registries (LIR). RIPE NCC is the administrative organization for European Internet resources (IP addresses/AS numbers).
LIR - Local Internet Registry
