Graceful Routing Engine Switchover Overview
The Graceful Routing Engine switchover (GRES) feature in the Junos OS enables a routing
platform with redundant Routing Engines to continue forwarding packets even if one
Routing Engine fails. GRES preserves interface and kernel information. Traffic is not
interrupted. For more information, on GRES, see the Junos High Availability Configuration
Guide.
•
To configure GRES on the JCS1200 platform, include the graceful-switchover statement
at the [edit chassis redundancy routing-engine] hierarchy level on the PSD.
•
Configure the graceful-switchover statement for all PSDs on the JCS1200 platform
that include redundant Routing Engines.
Graceful Routing Engine Switchover PIC Support
Junos OS Release 10.0 or higher supports GRES for PICs running on the JCS1200 platform,
including IQ2 PICs. IQ2 PICs supported on the JCS1200 platform include 1-, 4-, and 8-port
Gigabit Ethernet IQ2 PICs and 1-port 10-Gigabit Ethernet IQ2 PICs.
