You can perform a unified ISSU in one of three ways:
When you issue the request system software in-service-upgrade command with the reboot option, the system automatically upgrades both Routing Engines to the newer software and reboots both Routing Engines. This option enables you to complete the unified ISSU with a single command.
To perform a unified ISSU using the request system software in-service-upgrade package-name reboot command, complete the following steps:
