Configuration Expert adds the tunnel to the list of those found in the IP Tunnel
Configuration object. Before the SSR can use the tunnel for multicast routing, you need
to enable DVMRP on it as discussed in the next section.
Enabling or Disabling DVMRP on Tunnels
You can enable and disable DVMRP on the IP tunnels you previously created. To enable or
disable DVMRP on tunnels:
1.
Start Configuration Expert if you have not already done so.
2.
Open the configuration file you want to modify and then double-click that file's
Routing Configuration object.
3.
Double-click the IP Routing Configuration object.
4.
Double-click the IP Multicast Routing object. Then double-click the DVMRP Routing
object.
5.
Click the DVMRP Tunnels object. A DVMRP Tunnel dialog box similar to the
following appears:

Chapter 10: Configuring Multicast Routing on the SSR
Enter a number from 1 to 16 in the Metric box to specify the
metric (cost) of the interface.
Enter the speed at which you want outgoing traffic to pass
through the interface. The field's value is specified in kilobits
per second (Kbps).
Enter a number from 1 to 255 to specify the tunnel's multicast
Time to Live (TTL) Threshold box.
DVMRP uses the TTL to filter outbound traffic. Packets with a
TTL value less than the one you specify are not sent any further.
