clns router isis

isis circuit-type level-1

tunnel source Loopback1

tunnel destination 10.0.0.1

tunnel mode eon

Method two (tunnel mode gre)

interface Tunnel1

no ip address

clns router isis

isis circuit-type level-1

tunnel source Loopback1

tunnel destination 10.0.0.1

Many Thanks

Hello,

The encapsulation mode for the tunnel interface defaults to generic route encapsulation (GRE), so this command is considered optional. However, if you want a mode other than GRE, you must configure it by using the following command in interface configuration mode

tunnel mode eon.

EON, a standard for carrying CLNP over IP networks

EON is acronym for Experimental OSI (Open System Interconnection) Network
