I have created tunnel interface 3101 with source interface as Dialer 1 , now the tun 3101 is showing output drops while the dialer is clean.
I have tried to clear counters on tun 3101 but no use....can you please suggest what could be the reason for this and how can i solve this.
PLease note there is no impact as such as i am able to reach the detsination, but because of this our monitoring tool gives an alert which needs to be resolved ...
attaching you the sh run in tun 3101 , sh int tun 3101 and sh int dia 1 output
