Single ISG Router with a Single Cisco SCE Platform (1xISG – 1xCisco SCE)
illustrates a deployment using one ISG router with a single Cisco SCE platform.
Figure 13-1
Single ISG Router with a Single Cisco SCE Platform
Note the following:
•
The red dotted lines depict the control path communication.
•
A deployment of this type might be used with ISG running on a service gateway or BRAS
terminating a large number of subscribers. However, note that deploying only one Cisco SCE
platform results in a single point of failure, which is not generally acceptable in an actual
deployment.
Single ISG Router with Two Cascaded Cisco SCE Platforms (1xISG – 2xCisco SCE)
illustrates a deployment using one ISG router with two cascaded Cisco SCE platforms.
