LNS for PPP termination

Wed Feb 24, 2016 1:26 pm

Hi,
I want to run a CCR1009-8G-1S as LNS for a CDMA network. Setup is like a typical PPP dial in szenario with l2tp tunnel between LAC (CDMA PDSN) and LNS by use of a radius server with framed-ip as radius attribute. It looks like, that I bring up the l2tp tunnel and succeed with chap. When we come to the IPCP phase we are running into the timeout of 30sec + 5sec and l2tp tunnel is closed by Mikrotik. I have setup similar szenarios with Cisco vpdn without a problem. Are there limitations at Mikrotik?
Thx in advance
Richard

To give you an idea about the Cisco setup:
vpdn-group <domain>
description xxx
accept-dialin
protocol l2tp
virtual-template 3
source-ip xxx.xxx.xxx.xxx
lcp renegotiation on-mismatch




interface Virtual-Template3
description TEMPLATE <domain>
ip unnumbered Loopback0
no logging event link-status
no peer default ip address
no snmp trap link-status
ppp authentication chap callin XX-RADIUS
ppp authorization XX-RADIUS
ppp accounting XX-RADIUS
ppp ipcp dns a.a.a.a b.b.b.b

Any idea how to realize with Mikrotik?
Thx Richard

Hi Richard,

I was actually just researching something similar and I came across this incase it's relevant to your issue: http://forum.mikrotik.com/viewtopic.php ... 98#p439892

Just thinking aloud - may not be related at all!

I can confirm.

RouterOS 6.35 has proper LNS support.

Specific features added are:

- PPPoE over L2TP
- Support for "outer tunnel" authentication (L2TP auth)
- Support for pre-auth on the LAC

It has been successfully tested against IOS and IOS-XE by us.

Once there is support for Radius VSA to put ppp connection in a VRF we will likely move from Cisco ASR as LNS to Mikrotik CCR

Hi,
thanks for the answers. We are not running PPPoE but PPP over L2TP. Is this supported as well by Mikrotik?
Thx

We start using 1036 as LNS six months ago. Works fine. 800 Mbps for 25%CPU.

We are using LNS, PPPoE over L2TP tunnels, it works perfect and I recommend 6.39.1 as they have fixed couple of annpying bugs that was crashing some L2TP sessions in a special setup.
In our case Cisco is going out soon ;-)

Good job Mikrotik
