Chapter 10: Configuring Multicast Routing on the SSR
7.
Set the DVMRP parameters as discussed in the following table:
8.
Click OK.
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:
Table 17. DVMRP Parameters
Field
Description
Metric
Enter a number from 1 to 16 in the Metric box to specify the 
metric (cost) of the interface.
Rate
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).
TTL Threshold
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.
