information about supported line modules. See E120 and E320 Module Guide, Appendix
A, IOA Protocol Support for information about the modules that support BGP.
On ASIC-based line modules (OC48/STM16, GE-2, and GE-HDE line modules), you
can have a maximum of 8191 IP policy attachments and 8191 layer 2 policy attachments
for ingress policies per forwarding controller, and 8191 IP policy attachments and 8191
layer 2 policy attachments for egress policies per forwarding controller.
On FPGA-based line modules, you can have a maximum of 8191 IP policy attachments
and 8191 layer 2 policy attachments per forwarding controller.
CAM hardware classifiers are supported on OC48/STM16, GE-2, and GE-HDE ASIC-based
line modules. Policies that use CAM hardware classifiers consume one interface
attachment resource, regardless of the number of classifier entries in a policy.
Range vector classifiers, which include all software classifiers and FPGA-based hardware
classifiers, consume one interface attachment resource for every 32 classifier entries in
a policy.
The following examples illustrate how JunosE Software allocates interface attachment
resources. These examples apply to software and FPGA-based hardware policies:
A policy with 0 classifier entries consumes 1 interface attachment resource.
A policy with 1–32 classifier entries consumes 1 interface attachment resource.
A policy with 33–64 classifier entries consumes 2 interface attachment resources.
A policy with 65–96 classifier entries consumes 3 interface attachment resources.
A policy with 487–512 classifier entries consumes 16 interface attachment resources.
