Configuring IPv6 Multicast PFC3 and DFC3 Layer 3 Switching
The PFC3 and DFC3 provide hardware support for IPv6 multicast traffic. Use these publications to configure IPv6 multicast on Cisco 7600 series routers:
http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-multicast.html
http://www.cisco.com/en/US/docs/ios/ipv6/command/reference/ipv6_book.html
These sections provide additional information about IPv6 multicast support on Cisco 7600 series routers:
Features that Support IPv6 Multicast
These features support IPv6 multicast:
- RPR and RPR+ redundancy mode—See Chapter7, “Configuring RPR and RPR+ Supervisor Engine Redundancy”
- Multicast Listener Discovery version 2 (MLDv2) snooping—See Chapter32, “Configuring MLDv2 Snooping for IPv6 Multicast Traffic”
Note MLDv1 snooping is not supported.
- IPv6 Multicast rate limiters—See Chapter43, “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
http://www.cisco.com/en/US/docs/ios/12_2t/ipv6/ipv6_vgf.html
IPv6 Multicast Guidelines and Restrictions
These guidelines and restrictions apply to IPv6 multicast support on Cisco 7600 series routers:
– 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 7, “Configuring RPR and RPR+ Supervisor Engine Redundancy”)
– Ingress and egress PFC QoS (see Chapter 48, “Configuring PFC QoS”)
– Input and output Cisco access-control lists (ACLs)
– Partially switched IPv6 multicast flows
– Multicast RPF check for PIM-SM (*,G) traffic
– Manually configured IPv6 over IPv4 tunnels
– IPv6 multicast automatic tunnels
– IPv6-in-IPv6 PIM register tunnels

Using show Commands to Verify IPv6 Multicast Layer 3 Switching
These sections describe how to use show commands to verify IPv6 multicast Layer 3 switching:
- Verifying MFIB Clients
- Displaying the Switching Capability
- Verifying the (S,G) Forwarding Capability
- Verifying the (*,G) Forwarding Capability
- Verifying the Subnet Entry Support Status
- Displaying the Replication Mode Capabilities
- Displaying Subnet Entries
- Displaying the IPv6 Multicast Summary
- Displaying the NetFlow Hardware Forwarding Count
- Displaying the FIB Hardware Bridging and Drop Counts
- Displaying the Shared and Well-Known Hardware Adjacency Counters
Note The show commands in the following sections are for a router with a DFC3-equipped switching module in slot 1 and a Supervisor Engine 720 with a PFC3 in slot 6.
Verifying MFIB Clients
This example shows the complete output of the show ipv6 mrib client command:
This example shows how to display the MFIB client running on the MSFC:
This example shows how to display the MFIB clients running on the PFC3 and any DFC3s:
Displaying the Switching Capability
This example displays the complete output of the show platform software multicast ipv6 capability command:
Verifying the (S,G) Forwarding Capability
This example shows how to verify the (S,G) forwarding:
Verifying the (*,G) Forwarding Capability
This example shows how to verify the (*,G) forwarding:
Verifying the Subnet Entry Support Status
This example shows how to verify the subnet entry support status:
Displaying the Replication Mode Capabilities
This example shows how to display the replication mode capabilities of the installed modules:
Displaying Subnet Entries
This example shows how to display subnet entries:
Displaying the IPv6 Multicast Summary
This example shows how to display the IPv6 multicast summary:
Displaying the NetFlow Hardware Forwarding Count
This example shows how to display the NetFlow hardware forwarding count:
Note The Netflow (*, G) count is always zero because PIM-SM (*,G) forwarding is supported in software on the MSFC3.
Displaying the FIB Hardware Bridging and Drop Counts
This example shows how to display the FIB hardware bridging and drop hardware counts:
Note ● The (*, G/128) value is a hardware bridge entry count.
Displaying the Shared and Well-Known Hardware Adjacency Counters
The show platform software multicast ipv6 shared-adjacencies command displays the shared and well-known hardware adjacency counters used for IPv6 multicast by entries in FIB and ACL-TCAM.
