Hello Community, another conundrum that I am trying to solve - seems like I am very close to solution but there might be some concepts I don't have a full grasp on - so asking help from the community Here is a visual:
Below is all the related config I have on the L3 SW (CISCO 9300)
ip multicast-routing vrf SAT-EDGE distributed
interface Vlan106 ip vrf forwarding SAT-EDGE ip address 192.168.16.1 255.255.255.0 ip pim passive load-interval 30 end
interface Vlan254 ip vrf forwarding SAT-EDGE ip address 192.168.254.1 255.255.255.0 ip pim dense-mode ip igmp static-group 18.104.22.168 load-interval 30 end
My LAB is a little bit more complicated than this, but I wanted to simplify and FOCUS on what is not working actually. I don't have any equipment capable of IGMP so I am using mostly static configurations everywhere.
In a nutshell when I launch Multicast Traffic from the Source I am seeing it arrive on interface VLAN106 (I will actually have multiple sources eventually, such as VLAN 206, 306, etc... ) but the Receivers are all downstream of this VLAN 254 interface.
In the output of "ip mroute ..." I am not seeing an ingress interface and I am sure I am missing something either VRF Related configuration to support Multicast or vice-versa, but I can not seem to put my finger on it

Hi again Giuseppe seems like you are the main responder on my questions Thanks for that.
I tried all kinds of combinations, ip pim passive works fine as well because I have it set up further upstream (closer to the multicast source) and it does the job - but yes I have tried ip pim dense everywhere to no avail.
TTL is set properly as well - we discussed this in one of the previous posts
Any other ideas ? I mean I see the traffic coming in on VLAN 106 - I see Multicast packet count ... and since this interface and Interface Vlan254 are both in the same VRF I figured by forcing Vlan254 interface to send traffic out of it using the "ip igmp static-group" would actually work ... I even tried disabling ip igmp snooping for vlan 254 and 106 but still no luck
