Re: BGP

Marko,

The reason why i asked about load balancing was that if suppose i have 2
equal paths to the same AS and i use this bgp dmz-link bw feature , then the
bandwidth that i configure under the physical interface is only a attribute
which i can use to do load balancing. Will it impact the actual bandwidth of
the link. Sorry but i have not tried this in lab at the moment but will
definitely try it. Also if we use this feature in a live network that means
i cannot use any other attribute in the same AS to modify the path for
example Local pref because to use this feature all the path selection
attribute should be default.Please correct me if i am wrong here.

I was just trying to create different scenarios where if i use other BGP
attributes for path selection will this feature create a issue.

As far as load sharing is concerned, please correct me here that for ebgp
links the cli is maximum-paths x and for ibgp links is maximum-path ibgp x.

Thats all i know people. not much as you all but trying to learn a little
day by day. Once again thanks everyone for your valuable input.
