Integrated Switch Control Network Topology
Once the 22-port SCGE cards are installed, the control network topology ceases to be a simple
hub-and-spoke set of connections.
A control network topology provides the following functions:

Implementing the Integrated Switch Through ROMMON
When the 22-port SCGE comes out of reset, ROMMON must initialize the switches so that no loops get
formed and the processor can communicate with the rest of the system. ROMMON configures the
switches.

Test the FE links to all the rack hardware periodically.
Keep the local state information synchronized to the rack master.
Rearbitrate the shelf ownership if the primary router releases ownership.
Each RP in a line card chassis is connected to two different 22-port SCGE cards in a fabric chassis.
The 22-port SCGE cards are interconnected in a full mesh to provide an available control network
with multiple redundant Ethernet connections.
The 22-port SCGE cards appear to be a backbone in which different RPs are connected from the
outside.
Both the 22-port SCGE cards and RPs run the rapid spanning tree protocol (RSTP) to provide a
loop-free topology.
