[j-nsp] ISIS between T640 and Redback SE800

[david.roy at orange-ftgroup.com]

It's seems that is a Authentication issue. Indeed, we have LSP L2 authentication simple configured on the T640 and I've enabled the traceoption ISIS flag error : the logs displays this :

Jun 10 16:57:01.533962 ERROR: ISIS ignored a bad packet: L2 LSP id 0000.0a7b.820                                             8.00-00 from 0000.0a7b.8208 on interface ae8.1458 without authentication

So I've to find how to configure LSP authentication simple on the Redback.

Ok...  

So is this ethernet direct between the boxes?   No switch?  

Is it possible to sniff this traffic and see if there are errors coming out of the T box?
