hi team,
I have c9300 connected to SRX 340 via static route. I have also VRF on this switch with vrf default route through global. the VRF has source multicast and needs to get out through global routing table.
VRF config
po11
no switchport
ip vrf forwarding cust1
ip add 1.1.0.2/24
ip igmp static-group 235.1.1.1
ip pim sparse-mode
ing gi 1/0/1
des rp-VRF
ip vrf forwarding cust1
2.2.2.2/24
ip pim sparse-mode
int gi 1/0/11
des src-mcast
192.168.1.1/24
ip igm sparse-mode
ip pim vrf cust1 rp-address 2.2.2.2 235.1.1.1
ip route vrf cust1 0.0.0.0 0.0.0.0 Port-channel1 1.1.2.1 global
po1
description Connection to srx 340

ip route 0.0.0.0 0.0.0.0 1.1.2.1
ip route 1.1.0.0 255.255.255.0 Port-channel1
when I do show ip mroute cust1 235.1.1.1
(*, 235.1.1.1), 1d04h/stopped, RP 2.2.2.2, flags: SPF
Incoming interface: Null, RPF nbr 0.0.0.0
Outgoing interface list: Null
(192.168.1.2, 235.1.1.1), 1d04h/00:02:53, flags: PFT
Incoming interface: GigabitEthernet1/0/11, RPF nbr 0.0.0.0
Outgoing interface list: Null
is it possible to leak or force VRF traffic including multicast to go through global?
thanks in advance

check some reference guide : (based on what IOS XE and License you have on Cat 9300 ?)

appreciate the response and article. my configs are based pretty much on the instructions in the article and still does not work. I was wondering if this is a limitation of 9300?

do the debug and also check other side.

Hello
you static route towards the vrf cus is pointing to the wrong PC interface by the looks of it -
Also why are you showing different RP addressing?
maybe you could share a topographical diagram ?
