RE: Question on loopback interface

Hi Vamsi,

Unfortunately, there's no golden rule on this one as a number of other
elements in a topology can be affected by where you're allowed to advertise
your loopbacks (though - if someone does know of such a golden rule, please
share!). If the requirements restrict what you can do, then you obviously
have to satisfy these. If there are no restrictions, then you're able to put
them whereever you want.

Once you've identified what restrictions there are on your loopbacks (if
any), it is important to remember where your loopbacks are advertised. Best
make a note or mark them on your diagram to help you remember later in the
day. Also, by marking them on your diagram, hopefully you'll be able to spot
any potential upcoming pitfalls.

Cheers,
Gavin

Subject: Question on loopback interface

Hi,
   In the lab, on routers which perform redistribution between multiple
protocols, do we have any rule of thumb where the loopback interfaces will
be originated from ? The reason i am asking is, this can have some
consequences in later stages like multicast, etc. Just wanted to know what
is the best practice.
   I dont think the proctor can help here as it depends on our perspective
of the given scenario. Any pointers are appreciated.

Regards,
Vamsi
