OSPF + VRRP +PPPOE

Hello, i have a big l2 network, and whem somethin occurs in one side, make sense in other diferent side.
this is my scheme

provider1—ccr–pppoe------
_____SWITCH
/
provider2—ccr–pppoe------/

I whant to confi OSPF on it and VRRP to do redundancy, how can i do it?

thanks

just now i get works that

ISP1----- CCR1---------SWITCH_A -----CCR2---------------AP>>>>>> CLIENT

CCR1 is the border and know how to go 0.0.0.0/0 and CCR2 have the pppoe-server where the client make the connection,
now the client have output to internet, but, how can i add another ISP2----CCR3—SWITCH_A and config that one client i want to go throght isp1 and another one throught isp2?
thanks

You would use Routing Marks or VRFs to basically do source based routing. If you are using public IP space you’ll also need to adjust your advertisements so one range is used by ISP 1 and the other by ISP 2

Hi Joegoldman , in one ISP1 i have 4 /24 and onther ISP2 all is natted,
actually I can do the pppoe connection, and with the radius accept the call and , one client have a ip natted and another have public ip, but the client withc public ip sometimes go out ISP1 and other time go ISP2,
im new in that, can you say more how to make that router marks? i have search but dont take a good conclusion, if you have a reference, pleased to get it,
thanks a lot for your gold time!

more info,
i have 2 ccr, VRF as i can understand is for 1 ccr that marks depending of the ethernet?
how can i config it ?
thanks

hi again, nobody know how to get the solution?
thanks
