JUNOS OS 10.4 Release Notes
32
In Junos OS Release 10.3 and earlier releases, DHCP relay drops stray requests and
forwards a NAK to the client when authentication is configured. Otherwise, DHCP relay
attempts to bind the requesting client. In those releases, DHCP relay proxy always
drops stray requests and forwards a NAK to the client, regardless of the authentication
configuration.
You can override the new default configuration to cause DHCP relay and DHCP relay
proxy to drop all stray requests instead of attempting to bind the clients. To disable
automatic binding behavior globally, include the
[edit forwarding-options dhcp-relay overrides]
binding behavior for a group, include the statement at the

behavior for a specific interface in a group, include the statement at the

hierarchy level.
[Subscriber Access]
Support for VPLS Layer 2 wholesale configuration in a subscriber access
network—Enables you to configure Layer 2 wholesaling within a subscriber access
network. Wholesale access is the process by which an access network provider
(wholesaler) partitions the access network into separately manageable and
accountable subscriber segments for resale to other network providers. An access
network provider may elect to wholesale all or part of its network to one or more service
providers (retailers).
NOTE: In this release, Layer 2 wholesaling supports the use of only the
default logical system using multiple routing instances.
The Juniper Networks Layer 2 wholesale solution is similar to the Layer 3 wholesale
solution in many ways. However, when configuring the Juniper Networks Layer 2
wholesale solution, keep the following in mind:
No Layer 3 components (address assignment, Layer 3 interfaces, and so on) are
involved.
S-VLANs must be unique to any Gigabit Ethernet or Aggregated Ethernet interfaces
within the entire network (not just unique to one router).
Layer 2 wholesale supports only CoA disconnect and variable modification; CoA
service activation is not supported.
NOTE: For general information about configuring dynamic wholesale for
your subscriber access network, see the Broadband Subscriber Management
Solutions Guide.
