Feature Benefit

High-Performance

IP Routing

●

MPLS Traffic Engineering (TE) Fast Reroute (FRR) guarantees fast recovery after a link or node failure. FRR

protects MPLS networks from link and node failures by locally repairing the label switched path (LSP) at the

point of failure, rerouting all LSP traffic crossing a failed link over backup tunnels that bypass the failed link or

node

●

Cisco Express Forwarding hardware routing architecture delivers extremely high-performance IP routing.

●

Basic IP Unicast routing protocols (static and RIP versions 1 and 2) are supported for small-network routing

applications.

●

Advanced IP Unicast routing protocols (OSPF, EIGRP, IS-IS, and BGPv4) are supported for load balancing

and constructing scalable LANs.

●

IPv6 improves the scalability of IP networks by supporting the growing number of users, applications and

services. The functionalities supported include ACLs, DHCP, routing (Unicast routing, RIP, OSPFv3, static

routes), MLD snooping, stateless autoconfig, default router preference, HTTP/HTTPS.

●

Hot Standby Router Protocol (HSRP) provides dynamic load balancing and failover for routed links; up to 32

HSRP links are supported per unit.

●

Inter-VLAN IP routing provides for full Layer 3 routing between two or more VLANs.

●

BFD allows rapid detection of path and system failures by using a fast hello mechanism. BFD can provide

failure detection on any kind of path between systems. Routing protocols supported include OSPF, IS-IS,

BGP, HSRP and EIGRP.

●

Protocol Independent Multicast (PIM) for IP Multicast routing is supported, including PIM sparse mode (PIM-

SM), PIM dense mode (PIM-DM), and PIM sparse-dense mode. The Cisco IOS Software IP Services image is

required.

●

Cisco recommends 128 switch virtual interfaces (SVIs). A maximum of 1000 are supported (depending on the

number of routes and multicast entries).

Multicast

Efficient Multicast Distribution

●

Multicast VLAN Registration provides efficient multicast distribution in ring networks by dedicating a single

VLAN for multicast traffic, thereby removing duplicate multicast traffic in other VLANs.

●

PIM-SM provides efficient routing of multicast traffic by establishing distribution trees across WANs.

●

Source Specific Multicast (SSM) reduces the need for IP Multicast address management and prevents DoS

attacks against receivers.

●

SSM mapping provides a mapping of source to group, which allows listeners to find/connect to multicast

sources dynamically, reducing dependencies on the application.

Robust Multicast Control

●

IGMP Snooping helps enable intelligent management of multicast traffic by examining IGMP messages.

●

Multicast Listener Discovery (MLD) snooping v1 and v2 enables efficient distribution of IPv6 multicast data.

With MLD snooping, IPv6 multicast data is selectively forwarded to a list of ports that want to receive the data,

instead of being flooded to all ports in a VLAN.

●

IGMP Fast Leave provides a fast channel-changing capability for IPTV services.

●

IGMP filtering provides control of groups each user can access.

●

IGMP Throttling controls the maximum number of multicast groups each user can access.

●

IGMP Proxy allows users anywhere on a downstream network to join an upstream sourced multicast group.
