Configuring PPP and PPPoE
1.5 PPPoE Features
The SmartEdge OS implementation of PPPoE supports the following features:
• PPPoE encapsulation on Ethernet ports and ATM and 802.1Q PVCs.
• Both IP over Ethernet (IPoE) and PPPoE encapsulation on the same ATM
or 802.1Q PVC. You must specify multiprotocol encapsulation (the multi
keyword) for these circuits when creating the PVC.
• Policing and rate-limiting on a per-PPP-session basis.
• Rate-limiting the number of PPPoE PADI, PADR, or both messages on a
per-MAC address basis within a circuit.
• Ability to configure a maximum number of concurrent sessions allowed
on a circuit.
• Multiple simultaneous PPPoE sessions arriving over the same circuit while
being bound to different services (contexts).
• Ability to advertise a list of services (domains) to a client during the
discovery protocol.
• Ability to send messages to subscribers, including messages of the minute
(MOTMs).
• Ability to direct the subscriber’s browser to open at a specific, optionally
customized URL.
• Dual-stack session support for PPPoE subscribers and non-subscribers.
The SmartEdge OS supports PPPoE encapsulation on the following ports,
channels, and circuits:
• Ethernet ports
• ATM PVCs on ATM OC ports
• 802.1Q PVCs on Ethernet ports
• Child circuits on ATM and 802.1Q PVCs
1.6 Using IPCP Option 144 to Reserve IP Addresses and
Install Subnet Routes
Usually, residential customers need only a single reserved IP address, but
business subscribers require entire subnets to assign to their customers.
Using IP Control Protocol (IPCP) option 144, you can control which addresses
are reserved and which subnet routes are installed; Point-to-Point Protocol
over Ethernet (PPPoE) and Point-to-Point Protocol over Asynchronous
