Redundancy Connection for an M10i Router
Figure 287 on page 571 shows the connection between the master and backup Routing
Engines on an M10i router. Keepalive messages are sent between Routing Engines via
the interconnected HCM switches. In this way, the master and the backup Routing Engines
exchange state information.

Redundancy Connection for an M20 Router
Figure 288 on page 572 shows the connection between the master and backup Routing
Engines on an M20 router. Keepalive messages are sent between the master and backup
Routing Engine through the switch on the SSB. In this way, the master and the backup
Routing Engines exchange state information.
