[j-nsp] SSH/Telnet session hanging

[Muhammad Adnan Mohsin]

Hi,
I was still seeing ping drops without using the size. I adjust the MTU
size back to 1950 on this router. I don't see ping drops now but the
BGP behavior is now the same again. It's stable with one of the RRs
and still flapping with the other RR.

regards,
Adnan.
