You can treat it as p2mp. I put all the DCE ends of the cables on the Frame Switch so clock rate is defined there. However this is not a requirement. The FR Switch router does not need to have the DCE end. Regardless of the gender of the cable however the framerelay intf-type dce is required. I defined the DLCIs as Source Router 0 Destination Router. So if the circuit goes from R1 to R3 it s DLCI 103. From R3 to R1 it s DLCI 301. From Question 22 Subject What are the different types of memory used by Cisco Routers The 2500 Series and 7204 VXR have the same types of memory but they are implemented in different physical packages ROMMON - This is the initial bootstrap for the router. Boot Helper - This is a subset of IOS that is used to update software or network boot. The 2500 implements the ROMMON and boot helper in a set of two ROMs. The 7204VXR has ROMMON in a ROM and boot helper in a piece of flash memory on the I O controller called boot flash. Main memory - This is used to hold routing tables and IOS variables. In the 7204 VXR IOS itself is also resident in main memory. The 2500 Series usually runs the IOS directly in flash. Shared memory - This is the memory that holds packet .
