Our organization already has an ASN and is publishing our IP network in the Internet. We have an internet access in our site 1 with three ISPs.
Now we have to add a new site (site 2) that has two ISPs.
We are are thinking about using the same ASN in site 1 and site 2 but each site will publish its own IP network. The problem is that there is no IP connectivity between site 1 and site 2 (they can see each other only by Internet).
I think that ther is no problem to use the same ASN in both sites, the only objection seems to be that each site will drop the route to the other site (because this route ends in the same ASN) but I want to solve this issue adding a static route in both sites.
Do you believe tha it will be work properly?
