IP Sourcing

[ejgonzalesiii]

Normally when you telnet or tftp from a router, it sources the traffic with the exiting interface. Is there a way to change this default behavior so that you can source it from another interface like, for example, the way you can with ping and traceroute? I was hoping there was some kind of global command that did this.

There is not a single global command that will establish the source address. But there are a number of application specific commands that can do this. For example you can use these commands for the various applications:

ip domain lookup source-interface

ip ftp source-interface

ip flow-export source

ip ssh source-interface

ip tftp source-interface

ip telnet source-interface

ip tacacs source-interface

logging source-interface

ntp source

snmp-server trap-source

There probably are some others but these are the ones I could easily think of.

Hi

As already well pointed out by Rick,for telenting purpose you can also make use of the following command to select/opt the source interface.

PE1#telnet 10.1.1.2 /source-interface gigabitEthernet 1/1
