[cisco-bba] pppoe agregation ip problem.

Tue Oct 21 08:24:04 EDT 2008

Bonjour cisco-bba, 

We actualty want to use Alcatel Dslam and Cisco 10000 for Dsl aggregation.
Does any one work with two of them?

When ppp session come to CİSCO 10000 ,its send acces request to radius,if user is ok radius sending Access request Accept bras to give ip addres from DINAMIC
pool if user not authanticated radius give UNPOOL ip (10.1.1.0) for going to riderect page.

we are having problem and user not geting public ip adress.Bras sending two access request to radius but not full username,firstly sending just  ''@test.net'',
secondly send ''test1 at test.net'' format.Becouse of first format device not geting ip address from DINAMIC pool.
Iam sending config and radius debug.(user:test1 at test.net)
Thanks all.
