I have a question regarding BGP. Currently my sites configured with eBGP between them. In few months time, we are going to connect one of the site to ISP MPLS cloud.
My question is, for the site that are going to connect to ISP MPLS cloud, can it advertised all routes from its eBGP peer to ISP but only with its own AS number? Meaning to replace other eBGP peers AS number with the one connected to ISP once advertised out to ISP cloud
So from the ISP, they only see one AS number instead of many.
