Chapter 19 Viewing IP and MPLS Multicast Configurations
Viewing the Multicast Configurations
Viewing the Address Family (IPv6) Profile
To view the Address Family (IPv6) profile:
Step 1 Right-click on the required device and choose the Inventory option.
Step 2 In the Inventory window, choose Logical Inventory > Multicast > Address Family (IPV6). The profile
details are displayed in the content pane.
Table 19-4 describes the fields that are displayed in the Address Family (IPV6) profile.
Viewing the IGMP profile
The IGMP runs between hosts and their immediately neighboring multicast routers. The mechanisms of
the protocol allow a host to inform its local router that it wishes to receive transmissions addressed to a
specific multicast group. Also, routers periodically query the LAN to determine if known group
members are still active. If there is more than one router on the LAN performing IP multicasting, one of
the routers is elected querier and assumes the responsibility of querying the LAN for group members.
Based on the group membership information learned from the IGMP, a router is able to determine which
(if any) multicast traffic needs to be forwarded to each of its leaf sub networks. Multicast routers use this
information, in conjunction with a multicast routing protocol, to support IP multicasting across the
Internet.
Table 19-4 Address Family (IPV6) profile
Field Name Description
Interface All Indicates whether the multicast routing and protocols are enabled on the
interface.
Note You must enable the interfaces using the Interface command in
the multicast-routing configuration mode.
NSF Status Indicates whether the non-stop forwarding capability is enabled for all
the relevant components.
Note If this feature is enabled, then multicast forwarding will not stop
if the control plane multicast routing components fail.
Address Family The address family, which in this instance is IPV6.
MDT MLDP Indicates whether the Multicast Distribution Tree (MDT) Multipoint
Extensions to Label Distribution Protocol (MLDP) in-band signalling is
enabled.
MDT Static The interface used for transporting MDT data.
MDT Source Interface The source interface to set the multicast VPN data.
Note This interface can identify the root of the MDT in the service
provider network. This interface and its corresponding address
is used to update all Multicast VPN (MVPN) peers through
multiprotocol Border Gateway Protocol (BGP).
