Hello all,
We have a set up simplified as this:
Internet---[eBGP]---BR---[iBGP]---AR---[eBGP]---Cust_A
On the AR, we are receiving 2 routing paths to the customer's prefix:
[1] via Internet; 3 AS hops away
[2] announced from directly connected customer to AR; prefix is
prepended 7ASNs
Now as I understand it AR will not announce the unattractive prepended
prefix to the other local iBGP speakers in the network. And ultimately
not announce this block to the Internet.
Is there a way to circumvent this? The customer wants to 'see' us
announce the prepended announcement (although we have told them it will
be announced if the more attractive one is removed).
Thanks in advance.
