• IEEE 802.1ad QinQ and selective QinQ
Increases the scalability of an Ethernet network by providing a hierarchical structure; connects
multiple LANs on a high-speed campus or metro network
• Per-VLAN spanning tree plus
Allows each VLAN to build a separate spanning tree to improve link bandwidth usage in
network environments with multiple VLANs
• Isolation at data link layer with private VLANs
Provides, through a two-tier VLAN structure, an additional layer of protection, simplifying
network configuration while saving VLAN resources
Layer 3 services
• Address Resolution Protocol (ARP)
Determines the MAC address of another IP host in the same subnet; supports static ARPs;
gratuitous ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP
operation between subnets or when subnets are separated by a Layer 2 network
• 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 (RIP)
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 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)
• Border Gateway Protocol 4 (BGP-4)
Delivers an implementation of the Exterior Gateway Protocol (EGP) 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;
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; includes directed
broadcasts, customization of TCP parameters, support of ICNP error packets, and extensive
display capabilities
• Unicast Reverse Path Forwarding (uRPF)
Limits erroneous or malicious traffic in accordance with RFC 3074
