Refer to the exhibit.
The multicast sender and both multicast receivers are in the same VLAN. Multicast receiver 1 can
receive the multicast stream from the multicast sender, but multicast receiver 2 cannot receive this
stream. While troubleshooting IGMP, it is noticed that the IGMP report from receiver 2 is received
by switch 2 but not by switch 1.
Which action will solve this issue?
A.
Enable PIM on the SVI of the VLAN on switch DSW1 or switch DSW2.
B.
Add a straight connection between switch SW1 and switch SW2.
C.
Enable IGMPv3 membership reports on multicast receiver 2.
D.
Configure a rendezvous point on distribution switch DSW1 and distribution switch DSW2.
Enable PIM on the Layer 3 Router/VLAN Interface
All Catalyst platforms have the ability to dynamically learn about the mrouter port. The switches passively listen to either the Protocol Independent Multicast (PIM) hellos or the IGMP query messages that a multicast router sends out periodically.
This example configures the VLAN 1 switched virtual interface (SVI) on the Catalyst 6500 with ip pim sparse-dense-mode.
Switch1#show run interface vlan 1
!
interface Vlan1
ip address 1.1.1.1 255.255.255.0
ip pim sparse-dense-mode
end
