What is the IP address 141.1.25.5 ?

Can you ping the tunnel endpoint 141.1.0.5 ?

Have you tried traceroutes to verify the ping is taking the path you expect
it to?

Hi guys,
 
Can anyone explain what's going on here? When I ping the local end of
tunnel only some of the pings go thru.
 
Rack1R2#p 141.1.25.2
 
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 141.1.25.2, timeout is 2 seconds:

 tunnel destination 141.1.0.5
 
But, pinging the far side of tunnel goes thru 100% - no problem.
