L3 services
• Address resolution protocol (ARP)
Determines the MAC address of another IP host in the same subnet; includes support for static
ARPs; a gratuitous ARP allows detection of duplicate IP addresses; and a proxy ARP allows
normal ARP operation between subnets or when subnets are separated by an L2 network
• UDP helper
Redirects UDP broadcasts to specific IP subnets to help prevent server spoofing
• Dynamic host configuration protocol (DHCP)
Simplifies the management of large IP networks and supports both clients and servers; DHCP
relay enables DHCP operation across subnets
• Domain name system (DNS)
Provides a distributed database that translates domain names and IP addresses, simplifying
network design; and supports clients and servers
L3 routing
• Static IPv4 routing
Provides simple manually configured IPv4 routing
• RIP
Uses a distance vector algorithm with UDP packets for route determination; supports RIPv1
and RIPv2 routing; and includes loop protection
• 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
• IS-IS
Uses a path vector 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)
• BGP-4
Delivers an implementation of the exterior gateway protocol, utilizing path vectors; uses TCP
for enhanced reliability for the route discovery process; reduces bandwidth consumption by
advertising only incremental updates; supports extensive policies for increased flexibility; and
scales to very large networks
• Policy-based routing
Makes routing decisions based on policies set by the network administrator
• IP performance optimization
Provides a set of tools to improve the performance of IPv4 networks; and includes directed
broadcasts, customization of TCP parameters, support of ICNP error packets, and extensive
display capabilities
• Unicast reverse path forwarding
Limits erroneous or malicious traffic in accordance with RFC 3074
• 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
design to an IPv6-only network design
