Hi Community,
I need your help/thoughts regarding a multicast issue between a cisco switch (VSS) and a Fortigate firewall.
The mcast data is disseminated from the Cisco device to the Fortigate one , the issue is there are no heartbeats received on the far end and the Fortigate isn't able to build the (S,G).
The appropriate fwpolicies-mcast are in place and the "sh ip route" shows that data is being sent to the Fortigate device as below:
#sh ip mroute 232.0.x.x
Outgoing interface flags: H - Hardware switched, A - Assert winner, p - PIM Join
Timers: Uptime/Expires
Interface state: Interface, Next-Hop or VCD, State/Mode
(*, 232.0.x.x), 7w0d/00:02:55, RP 172.16.x.x, flags: SJC
Incoming interface: Null, RPF nbr 0.0.0.0
Outgoing interface list:
Te1/2/8.16xx, Forward/Sparse, 1w6d/00:02:55
(172.16.x.x, 232.0.x.x), 6w2d/00:02:28, flags: TA
Incoming interface: VlanX, RPF nbr 0.0.0.0
Outgoing interface list:
Te1/2/8.16xx, Forward/Sparse, 1w6d/00:02:55
PS: Te1/2/8.16xx is the interface facing the Fortigate
Both devices are working in a sparse-mode.
The multicast groups are defined in the boundary ACL under the cisco switch.
Thanks in advance.
