ASR 1000 about L2TP Session

[james-l]

I want to know how many L2TP session does ASR 1000 support? I can't find any answer from cisco official web site.

Chassis	RP	ESP	PPP Session	L2TP Tunnel
1001	Integrated	ESP-2.5G or ESP-5G	8000	4000
1001-X	Integrated	2.5G, 5G, 10G, or 20G	8000	4000
1002	Integrated RP1	ESP-5G	12000	6000
1002-X	Integrated	5G, 10G, 20G, or 36G	29000	16000
1004, 1006	RP1	ESP-10G or ESP-20G	24000	12000
1004, 1006	RP2	ESP-20G	32000	16000

So... is PPP session equal L2TP session by Cisco defined, right?

[Mark Malone]

They are 2 separate features but they can work together , l2tp supports ppp tunneling , it can encapsulate ppp frames and allow them to cross a packet switched network allowing ppp to be extended

[james-l]

Belowing the figure,establish LT2P session between LAC and LNS.I want to know how many session can support if ASR 1K is LNS role? Because the other vendor, juniper networks, provides this information for my client. I requested by my client to provide about this information,too.
