Create Network Scopes
Telco Return
Note If you are using the prepacketencode and postclientlookup .tcl scripts for telco return, the telco return
scope does not have a selection tag associated to the scope.
Step 1 Put the tag Telcocablemodem on the primary cable interface scope to pull addresses from that pool
instead.
Step 2 Follow the same procedure as above, but use a telco return policy which has a different .cm file with
telco-specific commands in it.
Create Network Scopes
Following is an example for creating scopes for your network. This example assumes two
