for DCN routing is seen as a strategically choice, which the operator
should configure prior to configure IP address and protocols on the
device. The reason for this is because the network design is
different for each of the system modes. The consequence for
changing the system mode from IP to IP un-numbered is
complicated and you may experience severe problems. Worst-case
scenario is not being able to re-obtain IP connectivity to NE.
2.3.4 Workaround
Generally the safest alternative is to erase the configuration prior to
change the system mode. We are aware that this is an unpopular
alternative, and have performed some testing to find a more proper
workaround.
NOTE! The following guidelines can not guarantee successful
change from IP to IP un-numbered System mode. It is
recommended that the configuration is tested on NE's in lab
prior to perform the changes in a live environment.
Up to now we have tested some different configurations, and the
following steps were successful:
1. Locally connect to MNGT-port and connect with AXX 9820
CRAFT.
2. Remove all IP addresses in the IP interface table except for the
MNGT-port address (IF=1000).
3. Remove all static configured routes (even the 0.0.0.0 route).
4. Disable active routing protocols (RIP and/or OSPF).
5. Locally connect to device via CLI (VT100).
6. Remove IP address assigned to management port
(AXXCLI>ip ip=0.0.0.0 sub=0.0.0.0).
7. Set system mode to IP unnumbered (IPUN) and reset the
device.
8. Change the IP address (MNGT-port) to fit your new network
design and re-configure the SNMP community.
9. Re-connect to device with AXX 9820 CRAFT.
