Cisco Network Registrar for the Cisco CMTS Routers

Procedure

Step 1

Create two scope selection tags such as: isp1-cm-tag and isp2-cm-tag

Step 2

Configure three scopes; for example, mgmt-scope, isp1-cm-scope, and isp2-cm-scope such that isp1-cm-scope

and isp2-cm-scope each define mgmt-scope to be the primary scope

Step 3

Also configure two scopes for PCs for each of the ISPs; isp1-pc-scope and isp2-pc-scope. For scope

isp1-cm-scope, configure isp1-cm-tag to be the scope selection tag. For scope isp2-cm-scope, configure

isp2-cm-tag to be the scope selection tag

Step 4

Configure two client classes; for example, isp1-client-class and isp2-client-class

Step 5

Create client entries with their MAC addresses for CMs that belong to ISP1 and assign them to isp1-client-class.

Also assign the scope selection tag isp1-cm-tag

Step 6

Create client entries for CMs that belong to ISP2 and assign them to isp2-client-class. Also assign the scope

selection tag isp2-cm-tag

Step 7

Enable client class processing from the scope-selection-tag window

Overlapping address ranges cannot be configured on these subinterfaces because software gleans the DHCP

reply to figure out the subinterface it really belongs to. Although CNR can be configured with overlapping

address range scopes, it cannot be used to allocate addresses from these scopes.
