Internet traffic through MPLS

Hello guys I'm back with another question:

My topology:

Mirko442_0-1673980554900.png

So for example if my internet link (g6/0) on CE-ST is down, I want traffic towards the ISP to go through MPLS (g1/0) to another CE router then through his internet link towards the ISP. I've tried redistributing default route from CE to PE in the routing protocols, then in BGP but I didn't understand it quite well, because when I redistributed default route from CE to PE it showed in vrf table but I couldn't ping 8.8.8.8.

but this same issue you mention solve before ? what new now ? 
the solution as you mention before solve by config static route toward MPLS router with high AD, 
here the trick can done by 
you use default route toward ISP and toward MPLS, 
the trick instead of redistribute any static route in MPLS you can use the NAT, 
NAT LAN to IP toward MPLS and in MPLS router redistruibute the connect. 
and that it. 

The previous question was to MPLS be primary route or PC's to communicate not internet, now I want traffic from PC to ISP to go through MPLS if internet link fails, I can't ping ISP from PC when internet link is down.

 

but I dont see any link between MPLS cloud and ISP router ? or there is some else ?

@MHM Cisco World Yeah I want traffic to go through MPLS to other CE router which has link to ISP.

Example: Internet link on CE-ST is shut, I want traffic to go through MPLS to 2 other CE routers (CE-MA or CE-IM) then through their internet link to ISP

 

ok, 
as I mention before, 
start with NAT the taffic in site A toward MPLS link 
then in PE connect to Central Site (that receive traffic from branch and forward it to ISP) use VRF route-target for import/export 

here the first part finish 
other part is are you run IPSec between the Central Site and ISP ?
if yes then you need to permit the MPLS link (mpls link because we hide the branch behind this link).

in ISP I think you need static route toward the central branch for the MPLS link. <<- this point I will think for other solution which I think will include add Lo in central site and NAT and MPLS link form branch to this LO and make ISP know only this LO instead of learn all MPLS link for all branch
