Overview
Layer 2 switching
Spanning Tree Protocol (STP)
fully supports standard IEEE 802.1D STP, IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) for faster convergence, and IEEE
802.1s Multiple Spanning Tree Protocol (MSTP)
Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) protocol snooping: effectively control
and manage the flooding of multicast packets in a Layer 2 network
Port mirroring: duplicates port traffic (ingress and egress) to a local or remote monitoring port
VLANs: support IEEE 802.1Q-based VLANs
sFlow: allows traffic sampling
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
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
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)
Interior Gateway Protocol (IGP) uses link-state protocol for faster convergence; supports ECMP, NSSA, and MD5 authentication
for increased security and graceful restart for faster failure recovery
Border Gateway Protocol 4 (BGP-4)
Exterior Gateway Protocol (EGP) with path vector protocol uses TCP for enhanced reliability for the route discovery process,
reduces bandwidth consumption by advertising only incremental updates, and supports extensive policies for increased
flexibility, as well as scales to very large networks
Intermediate system to intermediate system (IS-IS)
Interior Gateway Protocol (IGP) uses path vector protocol, 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
