Single ISG Router with Two Cascaded SCE Platforms (1xISG – 2xSCE)
Figure 14-2
Figure 14-2
This scenario is similar to the previous one, with ISG running on a service gateway or BRAS terminating
a large number of subscribers, however a second SCE platform has been added to provide redundancy.
This redundancy scheme assumes that SCE platforms are connected in a cascade, with one active SCE
platform and one backup.

When cascaded SCE platforms are connected to one or more ISG devices, only the active SCE
platform maintains a connection to the ISG devices.
You can configure the cascaded SCE platforms to receive session info from the SCMP peer on
session creation or pull the session info when the subscribers traffic traverses the SCE platform.
An ISG device cannot push sessions to two SCE platforms at the same time
