Standards compliance

The SR4134 implementation of PPPoE supports the PPPoE client
implementation specified in RFC 2516 - A Method for Transmitting PPP
over Ethernet (PPPoE).

.
IPsec over PPPoE is supported.
This implementation only supports client PPPoE.
PPPoE drops any data packets it receives if it is not the primary interface.
There is no ACL or VLAN support on PPPoE interfaces.
PPPoE cannot run on an Ethernet interface configured for VLAN
encapsulation.
QoS is not supported on PPPoE virtual access interface in this release,
but QOS can be configured on the parent Ethernet port.
The PPPoE client implementation cannot be used to connect to two
DSL connections for load sharing.
Neither unicast nor multicast routing protocols are supported on PPPoE.
When the IP address is negotiated with the PPPoE server, the PPPoE
client assumes that the subnet mask for the IP address is 32 bits wide.
The PPPoE virtual access interface is automatically configured in the
untrusted internet security zone. Configure the Ethernet interface on
which PPPoE is running in the internet security zone. To allow traffic to
pass through the firewall, at least one other router interface must be
configured in a trusted firewall zone (for example, corp).
