Hi
please, see the attached,
to sum up, Core#1 can't receive auto-rp information from firewall. I verified auto-rp mapping is successful on WAN.
in Core#1, RPF was successful for RP address, but, failed to map the auto-rp address.
the issue is there is Checkpoint firewall along the path. I confirmed there was no issue between cisco router platform.
I know this issue may reach to checkpoint but, I think it's general isssue we may have.
Lastly, we have the firewall aong the multicast path. PIM neighbor with firewall is successful, but failed to map auto-rp in Core#1.
which action, which we may need? can someone have similar setup like us?
