Figure 2-2 CSM Inline, MSFC Not Involved
This configuration has these characteristics:
• The MSFC is not routing CSM VLANs.
• All server-to-server communications (direct Layer 3 or load balanced) are through the CSM.
• The CSM must use static routes to the upstream router (default gateway).
CSM Inline, MSFC on Server Side
Figure 2-3 shows the CSM in a configuration where the MSFC is located on the server side.
Figure 2-3 CSM Inline, MSFC Located on Server Side
This configuration has these characteristics:
• Server-to-server direct communications bypass the CSM.
• Server-to-server load-balanced connections always require secure NAT (SNAT).
• The CSM must use static routes to the upstream router (default gateway).
• Routing protocols can be used in the back end.
• Layer 2-rewrite is not possible.
