PIM-DM (Dense Mode)

Feature Overview

PIM-DM on the switches covered in this guide includes:

■ Routing Protocol Support: PIM uses whichever unicast routing proto-

col is running on the routing switch. These can include:

• RIP

• OSPF

• Static routes

• Directly connected interfaces

■ VLAN Interface Support: Up to 128 outbound VLANs are supported in

the multicast routing table (MRT) at any given time. This means the sum

of all outbound VLANs across all current flows on a router may not exceed

128. (A single flow may span one inbound VLAN and up to 128 outbound

VLANs, depending on the VLAN memberships of the hosts actively belong-

ing to the flow.)

■ Flow Capacity: Up to 2048 flows are supported in hardware across a

maximum of 128 outbound VLANs. (A flow is composed of an IP source

address and an IP multicast group address, regardless of the number of

active hosts belonging to the multicast group at any given time.)

■ IGMP Compatibility: PIM-DM is compatible with IGMP versions 1 - 3,

and is fully interoperable with IGMP for determining multicast flows.

■ VRRP: PIM-DM is fully interoperable with VRRP to quickly transition

multicast routes in the event of a failover.

■ MIB Support: With some exceptions, PIM-DM supports the parts of the

Multicast Routing MIB applicable to PIM-DM operation. (Refer to “Excep-

tions to Support for RFC 2932 - Multicast Routing MIB” on page 3-42.)

■ PIM Draft Specifications: Compatible with PIM-DM draft specification,

versions 1 and 2.
