Mark, Saku,
Thanks for your help.
If you see the output provided we run one ebgp (full routing) and then we
have three ibpg (full routing).
We need to add one egbp due to high bandwidth needed and since we want to
use ibgp only in case of wan faults.
Can I run bgp multipath only on ebgp session?
We decided to add a link with the same carrier and we are aware we will not
reach 50/50 balancing.
What about RAM memory? Don t you see any issue?
Cheers
