1、保存现有的配置文件，并上传到FTP服务器上。

{master}[edit]
root@XX-MAN.RE0# save /var/tmp/config-old-20071127
Wrote 421 lines of configuration to '/var/tmp/config-old-20071127'

{master}[edit]
root@XX-MAN.RE0#run file copy /var/tmp/config-old-20071127
ftp://username:password@IP-address/config-old-20071127
Transferring ftp://username:password@IP-address/config-old-20071127 (5554 bytes): 100%
5554 bytes transferred in 0.0 seconds (4.71 MBps)

{master}[edit]

2、FTP上载8.3R3.4软件到主RE上。文件名类似"jinstall-8.3R3.4-export-signed.tgz"：

root@XX-MAN.RE0#run file copy ftp://username:password@IP-address/jinstall-8.3R3.4-export-signed.tgz
/var/tmp/jinstall-8.3R3.4-export-signed.tgz

  从主RE拷贝软件到备份RE，假定RE1是备份RE：

root@XX-MAN.RE0# run file copy /var/tmp/jinstall-8.3R3.4-export-signed.tgz
re1:/var/tmp/jinstall-8.3R3.4-export-signed.tgz

      确认软件已经拷贝到了设备/var文件系统下：

root@XX-MAN.RE0# run file list /var/tmp
/var/tmp:
.pccardd
install/
jbundle-8.3R1.5-export.tgz*
jinstall-8.3R3.4-export-signed.tgz
sampled.pkts
vi.recover/

root@XX-MAN.RE0# run show file list re1:/var/tmp
re1:
--------------------------------------------------------------------------
/var/tmp:
.pccardd
install/
jbundle-8.3R1.5-export.tgz*
jinstall-8.3R3.4-export-signed.tgz
vi.recover/

3、  对于双RE的系统将先升级备份RE。在升级备份RE后将切换RE使得原先的备份RE成为主RE。只有在确认了这个新的主RE一切正常后才会升级原先的主RE(即现在的备份RE)。这样即使出现问题仍可以退回到原先工件正常的主RE上。
     首先登陆到系统备用引擎上（这里为RE1）
     {master}
root@XX-MAN.RE0> request routing-engine login other-routing-engine

4、  升级备用引擎的操作系统，升级过程中的debug信息如下：
{backup}
root@XX-MAN.RE1>request system software add /var/tmp/jinstall-8.3R3.4-export-signed.tgz
cp: /var/tmp/jinstall-8.3R3.4-export-signed.tgz and /var/tmp/jinstall-8.3R3.4-export-signed.tgz are identical (not copied).

5、  确认升级没有出现异常信息，然后重起这个备用引擎完成升级
{backup}
root@XX-MAN.RE1> request system reboot
Reboot the system ? [yes,no] (no) yes


Rebooting lcc0-re1

Rebooting lcc1-re1


*** FINAL System shutdown message from root@XX-MAN.RE1 ***

System going down IMMEDIATELY






Shutdown NOW!
Reboot consistency check bypassed - jinstall 8.3R3.4 will complete installation upon reboot
[pid 9569]

6、  重起引擎后重新登陆到RE1上，察看系统的软件信息，确认备用引擎已经升级到了预期的版本
  
{backup}
root@XX-MAN.RE1> show version

7、  切换系统到RE1，使RE1为主用引擎，原来的主用RE0将变成备用引擎

{master}
root@XX-MAN.RE0>request chassis routing-engine master switch all-chassis

warning: Traffic will be interrupted while the PFE is re-initialized
Toggle mastership between routing engines ? [yes,no] (no) yes

lcc0-re0:
--------------------------------------------------------------------------

Complete. The other routing engine becomes the master.

lcc1-re0:

Complete. The other routing engine becomes the master.

{backup}
root@XX-MAN.RE0>

8、  按照升级RE1的步骤升级RE0（原来的主用引擎）
{backup}
root@XX-MAN.RE0> request system software add /var/tmp/jinstall-8.3R3.4-export-signed.tgz

cp: /var/tmp/jinstall-8.3R3.4-export-signed.tgz and /var/tmp/jinstall-8.3R3.4-export-signed.tgz are identical (not copied).

9、  确认版本达到了预期的结果后，把系统切换回原来的RE0，以消除系统告警信息

{master}
root@XX-MAN.RE1>request chassis routing-engine master switch all-chassis

warning: Traffic will be interrupted while the PFE is re-initialized
Toggle mastership between routing engines ? [yes,no] (no) yes

lcc0-RE1:

10、执行命令察看系统的运行状态，完成升级

show chassis hardware
show chassis environment
show chassis alarms
show chassis routing-engine
show chassis fpc
show chassis sibs
show interfaces terse
