Hello,
I have a cisco router 2821 with IOS c2800nm-ipvoice_ivs-mz.124-24.T3.bin.
The question is that I´m trying to configure a L2TP tunnel but the router don´t accept that I configure the interface Virtual-PPP1:
«
(config)#interface ?
Async Async interface
Auto-Template Auto-Template interface
BRI ISDN Basic Rate Interface
BVI Bridge-Group Virtual Interface
CDMA-Ix CDMA Ix interface
CTunnel CTunnel interface
Cellular Cellular WAN interface
Dialer Dialer interface
GigabitEthernet GigabitEthernet IEEE 802.3z
Group-Async Async Group interface
Lex Lex interface
Loopback Loopback interface
MFR Multilink Frame Relay bundle interface
Multilink Multilink-group interface
Null Null interface
Port-channel Ethernet Channel of interfaces
SSLVPN-VIF SSLVPN Virtual Interface
Serial Serial
Tunnel Tunnel interface
Vif PGM Multicast Host interface
Virtual-PPP Virtual PPP interface
Virtual-Template Virtual Template interface
Virtual-TokenRing Virtual TokenRing
range interface range command
vmi Virtual Multipoint Interface
(config)#interface vitual-PPP1
^
% Invalid input detected at '^' marker.
»
The pseudoeire is not even recognized:
«
(config)#pse?
% Unrecognized command
»
I already configure:
«
vpdn enable
ip cef
l2tp-class L2TP
authentication
»
In cisco site this IOS support L2TP. The router accept the command show l2tp

Hi,
I would recommend c2800nm-adventerprisek9_ivs-mz.124-24.T3. It's a superset of the -ipvoice_ivs- feature set that you have now, so you should not lose any IOS functionalities, see:

Hi,
Following is the configuration guide to configure L2TP on a cisco router
http://www.cisco.com/en/US/tech/tk801/tk703/technologies_configuration_example09186a00800946f5.shtml
Regarding (config)#interface vitual-PPP1
^
% Invalid input detected at '^' marker.

There is a typo at virtual .
It should be like interface virtual-ppp 1
Hope this helps!!
Thanks,

Sorry,
this is the correct copy/paste:
«
(config)#interface virtual-PPP 1
^
% Invalid input detected at '^' marker.

what code are you running on the router?
Can you paste the output of sh ver ?
http://www.cisco.com/en/US/docs/ios/dial/command/reference/dia_i1.html#wp1011879
The command was introduced in 12.3(2) T
Thanks,

Hi, Nelson:
The interface virtual-ppp and pseudoeire configuration requires the l2tpv3 pseudoeire-class feature, which is only available in the -entservicesk9-, -spservicesk9-, -advipservicesk9-, or -adventerprisek9- IOS feature sets. That's why you can't configure this in the -ipvoice_ivs- feature set as you have. You may want to upgrade the feature set and see if that helps.
Thanks,
Wen

This particular router is also a IP2IP gateway.
My afraid is that when I change the IOS some actual configuration is not recognized and the customer get the voip down (very critical).
The show version of the router is:

What IOS do you recommend ?
The idea is that this router work as a IP2IP and also have a 3G backup connection (that´s why I need to configure the tunnel).
