Re: Service Providers behaviour for dual homed enterprises

Many transit providers support BGP communities to modify how your announced routes are treated within their network. A quick search shows that AT&T supports BGP community 7018:70 to lower the default local-pref 100 down to 70 (below peer routes). If you tag your AT&T announced routes with BGP community 7018:70, then even AT&T customers should prefer to enter via Verizon. Clinton. On Wed, Sep 23, 2015, at 03:38 PM, Jason Bullen wrote:

So if my research is correct, the internet prefers Verizon UNLESS they are a direct AT&T customer then they would use the AT&T circuit. Is this a standard practice that I should assume to encounter?

Thanks in advance
