Configuring L2TP Client with No IPSEC/IKE on a ISR1100

[sabu123]

Hi

Hoping someone can help.

I have an ISR 1100 and would like to connect it as an L2TP client with no IPSEC no encryption. I have seen various posts but most are for IKE/IPSEC.

I'm struggling to configure the tunnel in terminal, some of the examples I have seen suggest using virtual-ppp but when I try to enter the menu I get "invalid input detected" 

I don't need it to route traffic over the L2TP, this is purely for testing that the router can authenticate with the LNS.

Any help is appreciated, the tunnel config is as follows: username: test password: test IP address of LNS: 10.20.1.2 CHAP or PAP

Thank you

Hi

Yeah PPP doesnt work:

Router(config)#interface Virtual-PPP1
                                 ^
% Invalid input detected at '^' marker.

 At this point I think my mind is made up. I will buy Mikrotik and paste 1 line in the file and it will work, or waste my evenings trying to get Cisco to work where I need 40 lines to do the same job.

Lets face it, this terminal interface is outdated and better equipment exists on the market at a fraction of the price.

Thanks

Router(config)#interface Virtual-PPP1 <<- Router(config)#interface Virtual-PPP  1

Router(config)#interface virtual-ppp 1

% Invalid input detected at '^' marker.

Although virtual-ppp is in the interface menu, it cannot be configured. Lol.

Hi

Yeah I don't have the correct type of account to download files like IOS I have tried. Meanwhile I can go on to Mikrotik website and download any sw I need. 

I will begin ripping Cisco out ASAP I am done with it lol To me it is now funny because I hear people say "buy Cisco its good equipment" and here we are poking around in a terminal session resembling the 70s.  I can get better equipment better support and a happier customer for a lot less hassle and money.

Hey @MHM Cisco World, I'm actually working on something very similar...

So far I have this but I don't interface come up or anything show in the L2TP server logs.  No ecryption, simple L2TP tunnel config. 

interface Virtual-PPP1
  description L2TP interface
  ip address negotiated
  ppp chap hostname username
  ppp chap password 0 ************
  ppp ipcp address accept
  pseudowire x.x.x.x 1 encapsulation l2tpv3 pw-class CORE_TRANSIT_TUNNEL


pseudowire-class CORE_TRANSIT_TUNNEL
  encapsulation l2tpv3
  ip local interface GigabitEthernet0/0/0

Really appreciate it!
