Hello,
   
  I have 2 routers connected via PPPoFR and also via serial interfaces with PPP authentication.
   
  When I configure the serial interfaces to be the backup for PPPoFR interfaces, the backup interfaces are not coming up.
   
  Below is my configuration,
   
  R1 (s1/0)--------PPP over framerelay----------(s1/0) R2
  | |
  |-----(s1/2)----- serial connection---------------(s1/2) |
   
  R1:
   
  interface Serial1/0
 no ip address
  backup interface s1/2
 encapsulation frame-relay
 frame-relay interface-dlci 504 ppp Virtual-Template1
  interface Virtual-Template1
 ip address 152.1.45.4 255.255.255.0
  interface Serial1/2
 ip address 152.1.54.4 255.255.255.0
 encapsulation ppp
 clock rate 64000
 ppp authentication chap
end
   
  R2:
  interface Serial1/0
 no ip address
  backup interface s1/2
 encapsulation frame-relay
 frame-relay interface-dlci 405 ppp Virtual-Template1
  interface Virtual-Template1
 ip address 152.1.45.5 255.255.255.0
  interface Serial1/2
 ip address 152.1.54.5 255.255.255.0
 encapsulation ppp
 ppp authentication chap
end
   
   
  Could anyone please help.
   
  Thanks,
  Vignesh
