HP MSR20-13-W JF808A Fiche De Données

3

• Excellent forwarding performance: provides

forwarding performance up to 160 Kpps; meets
current and future bandwidth-intensive application
demands of enterprise businesses

Resiliency and high availability

• Backup Center: acts as a part of the management

and backup function to provide backup for device
interfaces; delivers reliability by switching traffic
over to a backup interface when the primary one
fails

• Virtual Router Redundancy Protocol

(VRRP): allows groups of two routers to
dynamically back each other up to create highly
available routed environments; supports VRRP load
balancing

Layer 2 switching

• Spanning Tree Protocol: fully supports standard

IEEE 802.1D Spanning Tree Protocol, IEEE 802.1w
Rapid Spanning Tree Protocol for faster
convergence, and IEEE 802.1s Multiple Spanning
Tree Protocol

• 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: uses a distance

vector algorithm with UDP packets for route
determination; supports RIPv1 and RIPv2 routing;
includes loop protection

• 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 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: is an important element for the

transition from IPv4 to IPv6; 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

• 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, thus reducing
complexity and increasing performance; supports
graceful restart for reduced failure impact; supports
LSP tunneling and multilevel stacks
