Hi All,
In this task, it was required to configure SW1 to appear to BB3 as if it
was in AS 100. The solution guide solved it as follow:
On SW1:
router bgp 400
neighbor 204.12.1.254 local-as 100 no-prepend
This way, BB3 will see the routes received from SW1 with AS path 100
400.
The "no-prepend" option was used here to prevent SW1 from prepending
this imaginary AS number (100) to the routes received from BB3. I do
agree that this should be done.
My question is that using the "no-prepend" option was not explicitly
required in the task, will we lose points in a real lab exam for using
it. What if we used the "replace-as" option also. It could be used to
make BB3 sees the routes received from SW1 with AS path of 100.
