To my knowledge, all these are valid options. It just depends on what
you are asked to do in a scenario/work situation...
A) Dampen all routes from all sources to default values
B) Dampen all routes from all sources to specific values
C) Dampen specific routes to specific dampen parameters (could use
default parameters as well here)
D) Dampen specific routes from specific sources to specirfic dampening
parameters
The best thing I've learned in my studies so far is that ALL the options
we learn about have to deal with what I call "granular control". As you
notice, there are many ways to do things in the IOS, and they tend to
just highlight a finer degree of granularity over the function. As an
example, you have option A - D, each getting more granular and providing
you (the engineer) with a finer degree of control over that function.

Subject: BGP Dampening - Many Way of Configuration Scenerio
Hi all,
We can achieve the dampening configurations in many ways.
If we use route-map , case C) & D) , do we need to have "bgp dampening "
command under router bgp 1 ? How about case B) , after we set the
dampening value, do we need "bgp dampening" command under router bgp 1 ?
Regards.
A) Enable and use default value
--------------------------------
router bgp 1
bgp dampening
B) Enable and use defined value
--------------------------------
router bgp 1
bgp dampening 30 1500 10000 120
C) Enable and Use route-map
-----------------------------
route-map tag
match as path 10
set dampening 30 1500 10000 120
router bgp 1
bgp dampening route-map bgp-dampening
D) Bgp neighbor and route-map
-----------------------------
route-map tag
match as path 10
set dampening 30 1500 10000 120
router bgp 1
neighbor 171.69.233.52 route-map tag in
----------------------------------------------------------------
