Roman,

You could use l2tpv3 instead, works fine on 75xx.


With kind regards/ met vriendelijke groeten,

Subject: [c-nsp] Two LANs via STM-1.

	Hello!

I'm staying before interconnection two LANs via STM-1.
All I want - clean transport for a bunch of VLANs and IP routing on
devices connected to STM. May be not directly connected devices.

Solutions I'm currently working on are:

Two directly connected c7507 + RSP4 + VIP2-50(PA-FE-TX + PA-POS-OC3)
with EoMPLS and IP routing via POS.

Two 5005(5505) SE II + WS-X5167 (ATM Dual PHY OC-3 LANE/MPOA Module
(MMF)) +
WS-X5224 (24 FE) with LANE over that STM and routers on stick.

All old hardware due to cost limitation. I just can not afford new and
good hardware.

Questions I need advice on:

1. How stable EoMPLS at the moment? Will be RSP4 able to switch about
50-70 kpps? What bandwidth overhead I will have in this configuration?

2. Second solution looks more fundamental. But I never worked with ATM
and not sure that I need all that complexity in case of point to point
link.
Will it work in "back to back" configuration (without ATM switches on
the way)? Also what informational bandwidth I will have in this setup?

3. Is there is any other cost effective and flexible solutions for
interconnecting two LANs via STM-1?
