Features that Support IPv6 Multicast
Features that Support IPv6 Multicast
These features support IPv6 multicast:
• RPR and RPR+ redundancy mode—See Chapter 8, “Configuring RPR and RPR+
Supervisor Engine Redundancy.”
• Multicast Listener Discovery version 2 (MLDv2) snooping—See Chapter 29, “Configuring MLDv2
Snooping for IPv6 Multicast Traffic.”
Note MLDv1 snooping is not supported.
• IPv6 Multicast rate limiters—See Chapter 36, “Configuring Denial of Service Protection.”
• IPv6 Multicast: Bootstrap Router (BSR)—See the BSR information in the Cisco IOS IPv6
Configuration Library and Cisco IOS IPv6 Command Reference.
• IPv6 Access Services—See DHCPv6 Prefix Delegation—See this publication:
http://www.cisco.com/en/US/docs/ios/12_2t/ipv6/ipv6_vgf.html
• SSM mapping for IPv6—See this publication:

IPv6 Multicast Guidelines and Restrictions
These guidelines and restrictions apply to IPv6 multicast support on Cisco 7600 series routers:
• With Release 12.2(18)SXE and later releases, the PFC3 and DFC3 provide hardware support for the
following:
– Completely switched IPv6 multicast flows
– IPv6 PIM-Sparse Mode (PIM-SM) (S,G) forwarding
– Multicast RPF check for IPv6 PIM-SM (S,G) traffic using the NetFlow table
– Rate limiting of IPv6 PIM-SM (S,G) traffic that fails the multicast RPF check
– Static IPv6 multicast routes
– SSM Mapping for IPv6 (PIM-SSM)
– IPv6 multicast forwarding information base (MFIB) using the NetFlow table
– IPv6 distributed MFIB (dMFIB) using the NetFlow table
– Link-local and link-global IPv6 multicast scopes
– Egress multicast replication with the ipv6 mfib hardware-switching command
– Ingress interface statistics for multicast routes (egress interface statistics not available)
– RPR and RPR+ redundancy mode (see Chapter 8, “Configuring RPR and RPR+
Supervisor Engine Redundancy”)
– Ingress and egress PFC QoS (see Chapter 41, “Configuring PFC QoS”)
– Input and output Cisco access-control lists (ACLs)
