Trying to figure out how to handle routing internet traffic through branch office that has their own ISP however corporate office has default route set.
ISP <--- SITE A (Corporate Office) ---[MLPPP Link]--- SITE B (Branch Office) ---> ISP
A has a default route 0.0.0.0/0
B has A's default route through EIGRP
How can I have B route internet bound traffic through B's ISP and not through A's ISP?
Looking for any options. I would however like to have a failover back to A if B's ISP is down, or vise-versa.
A and B both have Cisco 3825's.
You can use distribute-lists within EIGRP to filter which routes, either outgoing or incoming on an interface, are allowed -
At site B add a static route with ISP (B)
ip route 0.0.0.0 0.0.0.0
If the ISP access link is down, it will use the EIGRP route through site A.
