ERX operating as an L2TP LNS will not negotiate multilink PPP with tunneled clients unless the LAC supplies proxy LCP information when establishing the tunnel.
Stray policies on L2TP LNS after shut/no shut of L2TP and bouncing subscribers
Windows clients are unable to establish MLPPP sessions with the ERX acting as an L2TP LNS
conf f filename.scr complains about L2TP LNS config
NAS-Port and NAS-Port-Type missing in L2TP LNS side of RADIUS access-request, acct-request and acct-stop messages
SM Line Card Reset FC recovery, reset type: panic task: Ingress FC[1] file: ngress/ifaNat.cc line: 215 after enabling ip port mirroring on an L2TP LNS.

L2TP LAC. Sessions/tunnels to an LNS drop, when bouncing sessions tunneled to a second LNS
ERX LAC sends L2TP ICCN packet that is rejected by LNS
L2TP ICRQs rejected by LNS because "system too busy".
L2TP flow control issues between a ERX LNS and a Cisco LAC.

LNS fails to reassemble L2TP Tunnel packets.
Reassembly failures on TSM in L2TP configuration with ERX as LNS.
If the L2TP tunnel is originated from LAC inside VPN VRF to the LNS inside VRF on a remote PE, PPP frames will be dropped on access line card after L2TP session have been estabilshed.
ERX LNS sends an incorrect MRU value after receiving an LCP config NAK for MLPPP clients over L2TP
Line Card Reset - Ping Failure Threshold Exceeded reset of the TSM line card after bring up a few hundred L2TP sessions
PPP magic number improperly handled for Proxy LCP at the LNS.
Cannot establish L2TP tunnel during 31-second "dead time"
L2TP tunnel switch fragmentation corrupting egress packets
L2TP sessions are dropped after SRP switch with HA active and the L2TP peer resynchronization method configured for silent-failover
Receiving a retrograde Nr from peer may cause a "stuck" L2TP tunnel
