Hi, I've little off topic suggestion regarding network design. The solution you are implementing will mean to make hundreds of users share= the same broadcast domain. As all your FTTH and other DSLAMS would be work= ing in bridge mode. This scenerio is not safe as if anyone of your clients will start his own p= ppoe server you will be in strange trouble, there can be other issues too. I guess your DSLAMs must have built in pppoe support and radius client, if = its there then every port of dslams can be separate broadcast domain. This = will cause you extra routing management (depending upon your scsnerio) In case your DSLAMS have no pppoe feature then i would suggest you to at le= ast put every DSLAM's uplink port in deparate VLAN and connect pppoe server= using trunk port or multiple single ports. And before implementing this solution consult your DSLAM vendor cause ive o= bserved problems in ipdslams when used in bridge/transperant mode.

Also I have a running PicoBSD box. Now I have a problem more grave... I am ongoing to install a CWDM (1GE) and DWDM=A0 (10GE)=A0 network=A0 for= =A0 the Alvarion BreezeACCESS VL (38 base stations) and more then=A0 200=A0 Iskrate= l FTTH DSLAMS of 96 ports (each with 100MBit, but only one=A0 1GE=A0 Upstream= ) each. What I now need are a PPPoE Severs (round-robin and loadbalancing) which must work using FreeRadius and PostgreSQL. There was someone on the <debian-isp> which=A0 has=A0 suggested=A0 me=A0 to= =A0 use FreeBSD, because the PPPoE it is already build to=A0 authenticate=A0 agains= t Radius. So, what I like to know is, if I have a 1GE and 10GE network,=A0 how=A0 man= y clients can=A0 one=A0 PPPoE=A0 Server=A0 handel=A0 and=A0 what=A0 are=A0 th= e=A0 CPU/Memory requirements? There is a little problem to get small but=A0 reliabel=A0 Servers=A0 with= =A0 TWO 10GE interfaces. I think, consumer mainboards are not suitabel even someone told me under Linux, I need 2 MHz CPU-Speed and 2 MByte of Memory per client... Please note, that I am ongoing ISP with over=A0 150.000=A0 customers=A0 in= =A0 DE between Freiburg and Karlsruhe (Baden-W=FCrttemberg)=A0 and=A0 using=A0 con= sumer mainboards is NOT reliabel since in the last 6 years I lost at least=A0 20 per year in 280 Low-Cost Servers. A "Sun Fire X4100M2" would be more reliabel... but even the smallest CPU would be overkill because the machine has only 1GE interfaces. Any suggestions? Note 1: Even if I use a Sun Fire, I would prefer a microBSD =A0 =A0 =A0 =A0 running from an industrial SD/CF card. Note:=A0 Please do NOT CC me, I am on the list and read it...
