Mulitcasting in PIM BSR Enviroment


R2 is the bsr router.
R3 and R4 are the RP candidates routers.
R7 will be acting like a multicast receiver and joining the groups 235.0.0.1 and 235.0.0.2
R5 or R6 will send multicast feeds to those groups.

-Since R7(multicast receiver) is requesting the multicast feeds for the 235.0.0.1 and 235.0.0.2, R4 has the *, group mroute entry for those groups.

Multicast Troubleshooting relating to RP

We will be using the same topology and config as the previous lab.
But in this lab I will raise the R3 candidate-rp priority value to 1 to make sure R4 is the RP used by all the routers.

R3 Config
ip pim rp-candidate Loopback0 priority 1

R1#show ip pim rp mapping

  Incoming interface: Null, RPF nbr 0.0.0.0
  Outgoing interface list:
    Loopback0, Forward/Sparse, 00:02:35/00:02:12

Then I will inject one fault which could lead R5 not being able to ping 235.0.0.1 to which address R7 is listening.


R5#ping 235.0.0.1 repeat 10

Type escape sequence to abort.
Sending 10, 100-byte ICMP Echos to 235.0.0.1, timeout is 2 seconds:
....

-It is failed. So let's try to check the RP mapping information and pim adjacency between R1 and R4.
We will see that R4(4.4.4.4) is the prefer RP to be used. We have pim adjacency between R1 and R4.
R4 has multicast receiver for 235.0.0.1 and 235.0.0.2. Then why it is failed at the first place.

-Now let's try to ping whether we can reach the RP address itself or not.

R5#ping 4.4.4.4

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 5.5.5.5, timeout is 2 seconds:
U.U.U
Success rate is 0 percent (0/5)

-We find that even though we have RP(4.4.4.4) information in the multicast routing domain wide, but in fact we don't even have the reach-ability to RP. It is really tricky, right. We have RP information that we can reach and essentially we are using that RP for multicast traffic forwarding.

-This is the fault I injected by not advertising the R4 Loopback0 network into OSPF.
So I will  correct this back.

R4(config)#int loo 0
R4(config-if)#ip ospf 1 area 0


-Now R5 can ping to RP and multicast feeds sending to 235.0.0.1 is successful.

R5#ping 4.4.4.4
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 24/57/92 ms
