Hello Experts,
HO Router:
---------------
!
interface Tunnel1
ip address x.x.x.x x.x.x.x
Tunnel Source x.x.x.x x.x.x.x
Tunnel Destination x.x.x.x x.x.x.x
Tunnel Mode IPIP
end
!
BO Router:
------------
!
interface Tunnel70
ip address x.x.x.x x.x.x.x
Tunnel Source x.x.x.x x.x.x.x
Tunnel Destination x.x.x.x x.x.x.x
Tunnel Mode IPIP
end
!
With the above Configuration, having Tunnel Mode as IPIP the interface IP Address of Tunnel is NOT PINGING. But the Source and Destination Address of the Tunnel is PINGING.
When, i removed the Tunnel Mode IPIP & re-create the Tunnel, the interface IP Address of the Tunnel started PINGING. Atlast, i tried re-adding the Tunnel Mode IPIP it worked even.
Whether after creating any Tunnel will the Router Processor creates some System Generated Routes or how ?
If i am not wrong, any Tunnel by default is GRE mode right ?
Thanks in Advance for your Answers.
Best Regards,
Guru Prasad R

It may be a encapsulation issue or any mode issues between devices verify that one.
