Multicast data on Cisco IR1101 router

[dennis_hs]

Hello Cisco Community.

I hope you can assist with the following multicast issue. It's probably really simple.

We have purchased a Cisco IR1101 industrial router (for a 'proof of concept' purpose), with a Gigabit port and four FastEthernet ports.

We are trying to pass multicast data from Gi 0/0/0 to VLAN 1.

From a factory reset, data is not transferred between Gi port to vlan 1. And we have unsuccessfully tried to configure the device to do so.

There is a lot of material out there, but nothing seemed to fit in.

Both cables in vlan 1 works as intended.

interface GigabitEthernet0/0/0
ip address 192.168.3.134 255.255.255.0

interface Vlan1:
ip address 172.16.3.1 255.255.0.0

If possible, what is the simplest way to pass multicast data from Gi 0/0/0 to vlan 1?

Thank you.

Hi

I don't know if ir1101 supports multicast, but the easiest way to test is to configure

ip multicast routing

int g0/0/0

ip pim sparse-dense mode

int vlan 1

ip pim sparse-dense mode

and then test if it works.

Be sure that the application do not use ttl=1, if so, it will not work.

Thank you for replying.

Unfortunately the above mentioned didn't work.

I don't know if it helps, but entering an interfaces gives the following ip multicast options:

Router(config-if)#ip multicast ?
    boundary Boundary for administratively scoped multicast addresses
    cca Commands related to Common Configuration Architecture (CCA).
    helper-map Broadcast to Multicast map OR Multicast to ip-address map
    limit Limit multicast mroute state
    rate-limit Rate limit multicast data packets
    ttl-threshold TTL threshold for multicast packets

I'm wondering if it is even possible at all....

But thank you for trying...

Hi

The ip multicast routing command is not an interface command. It should be configured globallly, so do exit from the interface prompt,
