And advertise one /25 to each provider. And the original /24 to both.
This way the incoming traffic would prefer one IPS for each /25 and in case of one ISP connection failure the whole /24 incoming traffic would use the other provider.
For the outgoing traffic:
This is more complicated.
The easiest way would be two HSRP or VRRP groups configured on the provider routers, one provider having higher priority in each group and tracking its WAN connection (decreasing the priority when the WAN connection fails).
You would configure a PBR on your router with a next-hop pointing to the virtulal IP address of the first/second group for traffic coming from the first/second /25.
I'm not sure though if the ISPs would agree to cooperate and share HSRP/VRRP groups together.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
