I need an advice about seperating internet traffic in "internet edge zone".
We have public ASN and use bgp to an ISP. My "internet edge zone" looks like this :
FIREWALL ETH1 ===> ETH1 BR01 ETH2 ===> ISP INTERNATIONAL LINK
ETH3 ===> ISP LOCAL LINK
Beetwen BR01 and ISP we use BGP, beetwen FIREWALL and BR01 we use static route and redistribute that route to BGP. Firewall have 0.0.0.0/0 to BR01 interface.
This configuration is okay, until i have a requirement to physicaly interface seperate some traffic from some building. Let say International 10Mbps for Building A and International the rest is 5 Mbps. I know i can do this in firewall, but how i do it in routing way / or bgp way ?
