High-Performance IP Routing
IP Routing Features
●
The VBS delivers extremely high-performance IP routing. IP routing features include:
●
Basic IP unicast routing protocols (Static and RIPv1 and v2) are supported for small-network
routing applications.
●
Advanced IP unicast routing protocols (OSPF, EIGRP, and BGPv4) are supported for load
balancing and construction of scalable LANs. The IP Services feature set is required.
●
IPv6 routing (RIP next generation [RIPng] and OSPFv3) is supported in hardware for
maximum performance. The Advanced IP Services feature set is required for IPv6 routing.
●
Equal-cost routing facilitates Layer 3 load balancing and redundancy across the stack.
●
Policy-based routing (PBR) allows superior control by facilitating flow redirection regardless
of the routing protocol configured. The IP Services feature set is required.
●
HSRP provides dynamic load balancing and failover for routed links. Up to 32 HSRP links
are supported per unit or VBS.
●
PIM for IP multicast routing is supported, including PIM sparse mode (PIM-SM), PIM dense
mode (PIM-DM), and PIM sparse-dense mode. The IP Services feature set is required.
●
Distance Vector Multicast Routing Protocol (DVMRP) tunneling interconnects two multicast-
enabled networks across nonmulticast networks. The IP Services feature set is required.
●
Fallback bridging forwards non-IP traffic between two or more VLANs. The IP Services
feature set is required.
Manageability
Management features
The VBS is managed as a single object and has a single IP address. The primary management
and control features include the following:
●
Cisco IOS Software CLI support provides a common user interface and command set with all
Cisco routers and Cisco Catalyst desktop switches.
●
Switching database manager templates for access, routing, and VLAN deployment allow the
administrator to easily maximize memory allocation to the desired features based on
deployment-specific requirements.
●
Cisco GOLD checks the health of hardware components and verifies proper operation of the
system data and control plane at run time and boot time.
●
Cisco IOS EEM allows customers to set up trigger points based on certain events to
automatically take actions, thus automating network management
●
VPN routing and forwarding (VRF) lite enables a service provider to support two or more
VPNs with overlapping IP addresses.
●
Local Proxy ARP works in conjunction with Private VLAN Edge to minimize broadcasts and
maximize available bandwidth.
●
VLAN1 minimization allows VLAN1 to be disabled on any individual VLAN trunk.
●
Smart Multicast, with Cisco VBS technology, allows the Cisco Catalyst Blade Switch 3130 to
offer greater efficiency and support for more multicast data streams such as video by putting
each data packet onto the backplane only once.
●
IGMP snooping for IPv4 and IPv6 Multicast Listener Discovery (MLD) Versions 1 and 2
snooping provide fast client joins and leaves of multicast streams and limit bandwidth-
intensive video traffic to only the requestors.
●
Multicast VLAN registration (MVR) continuously sends multicast streams in a multicast VLAN
while isolating the streams from subscriber VLANs for bandwidth and security reasons.
●
Per-port broadcast, multicast, and unicast storm control prevents faulty end stations from
degrading overall systems performance.
●
Cisco VLAN Trunking Protocol (VTP) supports dynamic VLANs and dynamic trunk
configuration across all switches.
●
Remote SPAN (RSPAN) allows administrators to remotely monitor ports in a Layer 2 switch
network from any other switch in the same network.
●
For enhanced traffic management, monitoring, and analysis, the embedded remote
monitoring (RMON) software agent supports four RMON groups (history, statistics, alarms,
and events).
●
Layer 2 traceroute eases troubleshooting by identifying the physical path that a packet takes
from source to destination.
●
Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by
enabling downloading from a centralized location.
●
Network Timing Protocol (NTP) provides an accurate and consistent timestamp to all intranet
switches.
●
Multifunction LEDs per port show port status.
●
Jumbo frames (9216 bytes) are available for advanced data and video applications requiring
very large frames.
●
SNMP v1, v2c, and v3 and Telnet interface support deliver comprehensive in-band
management, and a CLI-based management console provides detailed out-of-band
management.
●
Cisco Discovery Protocol Versions 1 and 2 enable a network-management station for
automatic switch discovery.
