[j-nsp] CISCO (LAC) & E120 (LNS) - L2TP

[Jake Jake]

We are trying to configure a Cisco (LAC) and E120 (LNS) to terminate PPPoE
sessions from end network over L2TP . Below is the configuration on the
LNS. Once the PPPoE session is initiated , we can see the tunnel build with
no sessions & L2TP logs are received on the LAC. LAC receives CDN's message
with "Error Code 4" stating "No resource" from the E120 router. On the E120
two tunnel shared ports are configured with a defined set of max-sessions.
Any suggestions on why E120 returns "No resource code"? E120 running on
10.2 code, however we don't have l2tp-session license enabled. But I
believe this is required to exceed the support of max-sessions to 32000.

If anyone has a working config for Cisco (LAC) & E120 (LNS) please do share.
