default routes

[MedTiti92]

Hi every one ,

I had some issues in my lab network, actually all my traffics users go to the internet throught the ISP-01 by defaut route like this : 

ip route 0.0.0.0 0.0.0.0 a.a.a.a, now i want to make another route to internet by another ISP-02 connected to this router ; please see below to understand well !

Hello
You can use Policy based routing for this?

Example ( excluding any NAT and assumption is the ISP2 connection is established) -
internal network - 192.168.1.0/24

ip access-list extended ISP2
deny ip 192.168.1.0 0.0.0.255 192.168.1.0 0.0.0.255
permit ip host 192.168.1.10 any

route-map PBR_ISP2
matich ip address ISP2
set ip next-hop <isp2)

int x/x
internal lan facing interface
ip policy route-map PBR_ISP2

Another alternative would be to place your "red" links into another VRF.

With either the PBR or VRF approaches, I believe it's possible to have one Internet default backup the other, but that does increase the complexity.

Thank you Guys for your answer, i think i will try with pbr first and see this solution, and have the vrf as second solution(Thanks Joseph W.)
