1.13 Configuring the Router by Copying Text
from a Terminal Window
Problem
You have a portion of a router configuration displayed in another window on your
terminal or computer and you want to copy it to another router and activate it.
Solution
Use the load merge terminal command:
aviva@router1> configure
Entering configuration mode
[edit]
aviva@router1# load merge terminal
[Type ^D at a new line to end input]
Then, cut the configuration snippet and paste it here. When you are done, type Ctrl-d.
Discussion
A time-saver when configuring the router is to cut the configuration text from one
window on your computer and paste it into the router’s terminal window with the
load merge terminal command. This is a great technique when you are copying configuration
text from a browser or email window or when you are propagating identical
or similar configurations from one router to another. To illustrate with a simple
example, suppose you are configuring PIM-SM on all routers and are copying the
configuration from a browser window. Here’s the configuration in the browser:
protocols {
pim {
interface all {
mode sparse;
version 2;
}
interface fxp0.0 {
disable;
}
}
}
Copy the text from the browser window; then, in the router’s configuration window,
go into configuration mode, move to the correct configuration hierarchy
level, and paste the text.
