[c-nsp] LFI Configuration

[Michele Marazza]

Hi All,

we are implementing LFI on low bandwidth ATM links (some hundreds of 100Kbps) and we are facing to
some two main problems:

1) very small percentuage of links shows output drops on the LAN interface when LFI is configured on
the ATM WAN link (tricky, isn't it? :-) )

2) traffic statistics are difficult because the number of the created Virtual-Access interface may vary.

Below I have two types of configuration, does one of it look like yours? Any other idea/suggestion
or experience with LFI?

Thanks
Regards
Mic

Ps: routers used 8xx, 1760
