QuickSpecs
Overview
User Datagram Protocol (UDP) helper
redirects UDP broadcasts to specific IP subnets to prevent server spoofing
Dynamic Host Configuration Protocol (DHCP)
simplifies the management of large IP networks and supports client and server; DHCP Relay enables DHCP operation across
subnets
Domain Name System (DNS)
provides a distributed database that translates domain names and IP addresses, which simplifies network design; supports
client and server
Layer 3 routing
Static IPv4 routing
provides simple manually configured IPv4 routing
Routing Information Protocol
uses a distance vector algorithm with UDP packets for route determination; supports RIPv1 and RIPv2 routing; includes loop
protection
Open shortest path first (OSPF)
delivers faster convergence; uses this link-state routing Interior Gateway Protocol (IGP), which supports ECMP, NSSA, and MD5
authentication for increased security and graceful restart for faster failure recovery
Intermediate system to intermediate system (IS-IS)
uses a path vector Interior Gateway Protocol (IGP), which is defined by the ISO organization for IS-IS routing and extended by
IETF RFC 1195 to operate in both TCP/IP and the OSI reference model (Integrated IS-IS)
Static IPv6 routing
provides simple manually configured IPv6 routing
Dual IP stack
maintains separate stacks for IPv4 and IPv6 to ease the transition from an IPv4-only network to an IPv6-only network design
Routing Information Protocol next generation (RIPng)
extends RIPv2 to support IPv6 addressing
OSPFv3
provides OSPF support for IPv6
BGP+
extends BGP-4 to support Multiprotocol BGP (MBGP), including support for IPv6 addressing
IS-IS for IPv6
extends IS-IS to support IPv6 addressing
IPv6 tunneling
allows IPv6 packets to traverse IPv4-only networks by encapsulating the IPv6 packet into a standard IPv4 packet; supports
manually configured, 6to4, and Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) tunnels; is an important element for
the transition from IPv4 to IPv6
Multiprotocol Label Switching (MPLS)
uses BGP to advertise routes across Label Switched Paths (LSPs), but uses simple labels to forward packets from any Layer 2 or
Layer 3 protocol, which reduces complexity and increases performance; supports graceful restart for reduced failure impact;
supports LSP tunneling and multilevel stacks
Multiprotocol Label Switching (MPLS) Layer 3 VPN
allows Layer 3 VPNs across a provider network; uses MP-BGP to establish private routes for increased security; supports RFC
2547bis multiple autonomous system VPNs for added flexibility
Multiprotocol Label Switching (MPLS) Layer 2 VPN
establishes simple Layer 2 point-to-point VPNs across a provider network using only MPLS Label Distribution Protocol (LDP);
requires no routing and therefore decreases complexity, increases performance, and allows VPNs of non-routable protocols;
uses no routing information for increased security; supports Circuit Cross Connect (CCC), Static Virtual Circuits (SVCs), Martini
draft, and Kompella-draft technologies
