NOTE:
• When an IPoE user comes online through an authorized VPN, you must configure a gateway IP
address or enable proxy ARP by using the proxy-arp enable command on the access interface.
As a best practice, enable proxy ARP. For more information, see proxy ARP configuration in
Layer 3—IP Services Configuration Guide.
• Leased users do not support AAA-authorized VPNs through ISP domains or AAA servers. For
more information about VPN authorization through ISP domains, see
Support for ITA
ITA provides accounting and bandwidth solutions for users based on the destination addresses they
access.
For more information about configuring ITA, see ITA configuration in BRAS Services Configuration
Guide.
Restrictions: Hardware compatibility with IPoE
Only CSPEX cards support IPoE.
IPoE supports the following interfaces:
•
Layer 3 aggregate interfaces/subinterfaces.
•
Layer 3 Ethernet interfaces/subinterfaces.
•
L3VE interfaces/subinterfaces.
Restrictions and guidelines: IPoE configuration
IPoE and IP source guard are mutually exclusive. For more information about IP source guard, see
Security Configuration Guide.
