Virtual-Template Interfaces (VTI) types

[satv]

Hello !

I need some inputs on Virtual-Template interfaces.

1) What are the most used configurations( set of clis)  for all the 3 types of VTI interfaces  1)  Type Serial 2) type Ethernet 3) Type Tunnel ?

2) What scenarios each of these 3 types of VTI are used ?

Hi,

I am not so familiar with Serial and Ethernet type Virtual Template interfaces but you can read a bit more about them in general here:

http://www.cisco.com/en/US/docs/ios/12_0/dial/configuration/guide/dcvtemp.html

Tunnel type VTI are generally used with EZVPN and this link would give information and configuration examples for both static and dynamic VTI (dynamic VTI uses the virtual template interface, static vti uses tunnel interface):

I hope this helps.

Warm Regards,

Rose

Thanks Rozsa,I have come up this cli set.

1)      type serial

interface virtual-template type serial

encapsulation {ppp|frame-relay|slip}

mtu

bandwidth

full-duplex|half-duplex

ip address {secondary}

ip unnumbered

ip address pool

ip address negotiated [previous ]

ip address dhcp client-id {Port-channel | GigabitEthernet } {hostname }

2)      type tunnel

interface virtual-template type tunnel

ip address {secondary}

ip unnumbered

ip address pool

ip address dhcp client-id {Port-channel | GigabitEthernet } {hostname }

tunnel source {ip-address | interface-type interface-number}

tunnel destination
