You use static routes for connectivity to the ISP. Your ISP recently switched to using different links
for multicast and unicast traffic. Following the change, users in your company were unable to receive
multicast traffic through the ISP. What must you configure on your router to reestablish multicast
connectivity to your ISP?
A.
Add a static default route to the ISP in the inet.2 routing table.
B.
Add the default-rpf-interface parameter under the [edit routing-options multicast] hierarchy.
C.
Add the upstream-interface parameter under the [edit protocols pim] hierarchy.
D.
Disable PIM on the interface used for unicast traffic.
