Viewing the PIM next-hop table

The PIM next-hop table is also very useful for checking the various states, it can be used to quickly identify the states of multiple multicast streams

FGT-3 # get router info multicast pim sparse-mode next-hop Flags: N = New, R = RP, S = Source, U = Unreachable Destination Type Nexthop Nexthop Nexthop Metric Pref Refcnt Num Addr Ifindex

10.166.0.11 ..S. 1 10.132.0.156 9 21 110 3

192.168.1.1 .R.. 1 10.132.0.156 9 111 110 2

Viewing the PIM multicast forwarding table

Also you can check the multicast forwarding table showing the ingress and egress ports of the multicast stream.

FGT-3 # get router info multicast table

IP Multicast Routing Table

Flags: I – Immediate Stat, T – Timed Stat, F – Forwarder installed

Timers: Uptime/Stat Expiry

Interface State: Interface (TTL threshold)

(10.166.0.11, 239.255.255.1), uptime 04:02:55, stat expires 00:02:25

Owner PIM-SM, Flags: TF Incoming interface: port2

Outgoing interface list:

port3 (TTL threshold 1)

Viewing the kernel forwarding table

Also the kernel forwarding table can be verified, however this should give similar information to the above command:

FGT-3 # diag ip multicast mroute

grp=239.255.255.1 src=10.166.0.11 intf=9 flags=(0x10000000)[ ] status=resolved last_assert=2615136 bytes=1192116 pkt=14538 wrong_if=0 num_ifs=1 index(ttl)=[6(1),]
