Challanging PBR for Dialers

Dear Community Members,

 

I have a challanging scenario for two dialers on two different routers

     Dialer1 (ppoe)                                    Dialer2 (ppoe)

    /                                                          /

R1-(Active)----Sw1--(HSRP)--Sw2 ------R2

    \                                                          \

     Leased Line 1---------(eBGP)---------- Leased Line 2

 

Between R1 & R2 i-bgp is also there

Requirement:

* if dialer1@R1 fails , traffic should go to dialer2@R2

* if dialer2@R2 fails, traffic should go to dialer1@R1

Following is the ip sla, track & pbr for both routers

 

R1

track 123 ip sla 1 reachability
track 124 ip sla 2 reachability
track 125 ip sla 3 reachability

 

ip sla 1
 icmp-echo 83.111.161.173 source-interface FastEthernet0/0
 frequency 5
ip sla schedule 1 life forever start-time now

ip sla 3
 icmp-echo 8.8.8.8 source-interface Dialer1
 frequency 5
ip sla schedule 3 life forever start-time now

 

route-map PBR-Internet permit 6
 match ip address 30
 set ip next-hop verify-availability <RTR2-ip> 10 track 125
route-map PBR-Internet permit 10
 match ip address 10
 set ip next-hop verify-availability RTR2 10 track 124
 set ip next-hop <isp1-ip>

 

RTR2

track 125 ip sla 3 reachability

ip sla 3
 icmp-echo 8.8.8.8 source-interface Dialer1
 frequency 5
ip sla schedule 3 life forever start-time now

 

route-map PBR-Internet permit 1
 match ip address 10
 set interface Dialer1

 

routing traffic for specific IPs to dialer 1 & 2 works, but in case of either of the dialers failure no redundancy is there.

 

I need help to address this challange, any help is highly appreciated.....
