In this demo, we'll set up an IPv6 PIM SSM flow and see it in action,
we'll use MLDv2 to request an SSM flow and send traffic from that source,
lastly,
we'll see the first‑hop router and last‑hop router's multicast
route tables to understand the traffic flow.
The first thing we need to do is set up our receiver to issue an
MLDv2 report asking for our source and group.
We'll use an SSM group and ask for the IPv6 address for our source.
Moving over to the last‑hop router,
we just need to check and see that the MLDv2 report was received.
It looks good here. Let's start sending source traffic, and it
should be successful. On the source, just ping the SSM group, and
the first‑hop router should already have the outgoing interface list
towards our downstream receiver.
Okay, these look successful.
Now to look at the first‑hop router and route table.
Okay, here's the S, G for the flow.
Notice that our incoming interface is connected to the
source and our outgoing interface is to MCAST2, which is
the shortest path to our receiver.
Last, let's jump over to the LHR, last‑hop router,
and check out its mroute table.
Okay,
It looks like it also has the S, G for this stream, no rendezvous point needed, and traffic was delivered.
