[c-nsp] If BGP is running on a circuit, if you ping the other end you get loss. kill the BGP (and thus the traffic..) no more loss.

[Vincent De Keyzer]

Just checking: you don't have any duplex (HD/FD) problem on Ethernet, 
right? "Ping works with no traffic but does not work when traffic " is 
typical of duplex problems.

Of course, if this also happens with POS, it must be something else; but 
I wanted to check...
