When i copy start up config to running config on my router remotely i lost the connection for few mins and when i got connection back
i saw this in logs
Apr 3 05:08:05.219 MST: %DHCP-6-ADDRESS_ASSIGN: Interface FastEthernet0/0 assig ned DHCP address 96.51.x.x, mask 255.255.252.0, ).
Apr 3 05:13:10.065 MST: %DHCP-6-ADDRESS_ASSIGN: Interface FastEthernet0/0 assig ned DHCP address 96.51.x.x, mask 255.255.252.0, hostname 2650xm
my interface fa0/0 connects to isp cable modem.
i telnet to router using public ip 96.51.x.x..
any idea why this happened?
To reiterate, when you make changes in the running-config, the correct command is
copy run start
copy start run
When you copy the startup-config to running-config, the startup config may overwrite changes made in the running-config.
These changes may affect connectivity to your router. As you are obtaining the IP address via DHCP, the startup-config may have saved a different IP address from a previous instance...
It can also be due to the fact that if you type 'ip address dhcp' under the physical interface, the DHCP client may be restarted and connection to the router via this interface may be suspended until a new lease is obtained. Again, typing that command or overwriting the config with the command in it, will cause the same effect.
