Chapter 5 Software Upgrade Processes Supported by Cisco ASR 1000 Series Routers
ISSU Upgrade for Redundant Platforms
Step 2 Install the RP subpackages from the directory simultaneously by using a wildcard statement to capture
all of the RP subpackages. This command should capture the RPControl, RPAccess, and RPIOS
subpackages without capturing the RPBase subpackage and should be done using the standby bay.
Use the asr1000rp1-rp*version.pkg syntax instead of using the {pattern} syntax to complete this
upgrade:
request platform software package install rp 1 file
stby-bootflash:asr1000rp*02.02.01.122-33.XNB1*.pkg bay 1 force
Step 3 Wait for the system to reach SSO ready state. The show platform command can be used to monitor
whether both IOS instances are active, and a system message will indicate SSO state has been reached.
Step 4 Use the redundancy force-switchover command to trigger an IOS switchover.
Step 5 Wait for the system to reach SSO ready state. Like in step 3, the state can be monitored by checking
system messages or by entering the show platform command.
Step 6 Install the RP subpackages from the directory simultaneously by using a wildcard statement to capture
all of the RP subpackages. This command should capture the RPControl, RPAccess, and RPIOS
subpackages without capturing the RPBase subpackage and should be done using the standby bay.
Use the “asr1000rp1-rp*version.pkg syntax instead of using the {pattern} syntax to complete this
upgrade:
request platform software package install rp 0 file
stby-bootflash:asr1000rp*02.02.01.122-33.XNB1*.pkg bay 0 force
Step 7 Install the SIPBASE and SIPSPA packages on each SIP:
Router# request platform software package install rp 0 file
bootflash:asr1000rp1-sip*02.02.01.122-33.XNB1*.pkg slot 4 force
Router# request platform software package install rp 0 file
bootflash:asr1000rp1-sip*02.02.01.122-33.XNB1*.pkg slot 1 force
Router# request platform software package install rp 0 file
bootflash:asr1000rp1-sip*02.02.01.122-33.XNB1*.pkg slot 2 force
Step 8 Install the ESPBASE package on the ESP:
Router# request platform software package install rp 0 file
bootflash:asr1000rp1-esp*02.02.01.122-33.XNB1*.pkg
Step 9 Copy the RPBase subpackage into the directory, then upgrade all of the RP subpackages simultaneously.
This step will upgrade the RPBase subpackage, which is the last remaining subpackage that requires an
upgrade:
request platform software package install rp 1 file
bootflash:asr1000rp*02.02.01.122-33.XNB1*.pkg force
Step 10 Enter show version provisioned to confirm that all of the software has been updated.
Step 11 Reload the router using the reload command when appropriate to complete the installation.
Downgrades in versions that do not support the {pattern} syntax are problematic because an
RPBASE package for the downgrade version will always be present if an upgrade was
previously performed. Removing and restaging all packages will work in this case, but they
effectively put the system into a state where if the RP reloads prior to the installation
being completed, the RP may no longer be bootable.
