Self ip of WAN interface not pingable

Hi,

  I have an Internet Gateway with dual homed to 2 ISP's terminated in 2 different routers in my end. My end routers are 7606 routers.

  I have a WAN link from Router 1 to ISP1 and from Router 2 to ISP2.

  Router 1:

  -------------

  int Gi1/1

  description " Link to ISP1"

  ip address x.x.x.142 255.255.255.252

  x.x.x.141 is configured in ISP end router.

  The problem I m facing is that I m not able to ping x.x.x.142 from this router. But x.x.x.141 is pingable.

  Also when I check from any internet route server, I m able to ping both x.x.x.142 and x.x.x.141.

  Please let me know the possible reasons for the same.

  Regards,

  Muthu.

Self ip of WAN interface not pingable

Hi!

Do you have unicast rpf check enabled on the interface?

1] like command "ip verify unicast source" ? if yes then just add "self-ping" to it so it will work.

or

2] check if any control plane policy is in place.
