    Hi All,

    I am configuring a GRE tunnel from Local controller ot DMZ controller, it is reachble and able to ping each other.

    After configuring GRE tunnel I can see that "ENCAPS" is going high in DMZ side and "DECAPS" is going high in Local controller side.

    But encaps in local controller is not increasing and decaps in DMZ controller is not increasing.

     

    Local controller config:

    interface tunnel 100

    tunnel source "local mgmt  ip"

    tunnel destination " dmz mgmt ip"

    tunnel mode gre 1

    tunnel keepalive

    trusted

    tunnel vlan "l2 vlan"

     

    DMZ controlle config:

    interface tunnel 100

    tunnel source " dmz mgmt ip"

    tunnel destination " local mgmt ip"

    tunnel mode gre 1

    tunnel keepalive

    trusted

    tunnel vlan "l2 vlan"
