@greenpau ... silly question, you do have a unicast routing protocol running underneath, right?
@troglobit, bgp :-)
OK :smiley:
If that is the msend
I think it is, then its default TTL is set to 1 ... which means no router would forward that data. Try adding -t 255
to the command line of msend
, or an appropriate amount representative of the router depth in your setup.
@troglobit, there are two routers connected via GRE tunnel:
R1
andR2
.R1
is RP.R2
send multicast packets to the group address of239.2.2.10
:R1
sees the packets arriving when listening on its tunnel interface:The issue arose when sending traffic to another interface of
R1
. It does not forward the packet over.Troubleshooting:
R2
, checked multicast forwarding:The same on
R1
:Also, checked the following
Other tunnels work fine.
Any ideas?
