In this case, sessions are migrated from node to node. Under normal operating conditions, traffic is processed by only node 0. A failure of interface ge-0/0/0 on node 0 causes a change in the routing table, so that it now points to interface ge-4/0/0 in node 1. After the failure, sessions in node 0 become inactive , and the passive sessions in node 1 become active. Traffic arriving from the Trust zone is still received on interface fe-1/0/0, but is forwarded to node 1 for processing. After traffic is processed in node 1, it is forwarded to the Internet through interface ge-4/0/0.
In this chassis cluster configuration, redundancy group 1 is used to control the reth interface connected to the Trust zone. This redundancy group (and, therefore, reth0) fails over only if interface fe-1/0/0 or fe- 5/0/0 fails, but not if any of the interfaces connected to the Internet fail.
