Configuring ISG Access for IP Subscriber Sessions
How to Configure ISG for IP Subscriber Sessions
25
Prerequisites
For ISG to use DHCP to assign IP addresses, the following prerequisites must be met:
•
The subscriber must be Layer 2 connected.
•
ISG must be in the path of DHCP requests, serving as a DHCP server or relay.
•
The appropriate IP subnets must be configured on the subscriber interface.
The tasks in this section assume that you have configured DHCP support in your network.
Configuring an ISG Interface for Dynamic DHCP Class Association
Perform this task to enable ISG to influence the assignment of IP addresses to subscribers on the
interface by providing the local DHCP component with a class name. The class name refers to a class
configured using the ip dhcp pool command and can reference a pool of addresses or a relay destination.
SUMMARY STEPS
1.
enable
2.
configure terminal
3.
interface type number
4.
ip address ip-address mask [secondary]
5.
ip subscriber [l2-connected | routed]
6.
initiator dhcp class-aware
7.
end
DETAILED STEPS
Command or Action
Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
•
Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
interface type number
Example:
Router(config)# interface gigabitethernet 0/0/0
Specifies an interface for configuration, and enters interface
configuration mode.
Step 4
