Tiered Network with BPX Switch and IGX Switch Routing Hubs
BPX Routing Hubs in a Tiered Network
Tiered networks with BPX routing hubs have the capability of adding interface shelves/feeders
(nonrouting nodes) to an IGX/BPX routing network as shown in Figure 1-7. Interface shelves allow the
network to support additional connections without adding additional routing nodes.
The MGX 8220 or MGX 8800 and IGX 8400 nodes configured as interface shelves are connected to BPX
routing hubs.
The MGX 8220 and MGX 8800 support frame T1/E1, X.21 and HSSI Frame Relay, ATM T1/E1, and
CES.
