Procedure
Step 1
Cut and paste the scope selection tag create commands from the scripts into the nrcmd> command line.
These names have to be exactly as they appear in the scripts.
Note
Step 2
Then attach the selection tags to the appropriate scripts:
Example:
CM_Scope tagCablemodem
PC_Scope tagComputer
Telco Return for the Cisco cBR-8 Router
Before You Begin
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.
Note
Procedure
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.
Creating Network Scopes
Following is an example for creating scopes for your network. This example assumes two Cisco cBR-8
converged broadband routers in two locations, with one cable interface card on one Cisco cBR-8 configured
for telco return.
