[j-nsp] SSH/Telnet session hanging

[Muhammad Adnan Mohsin]

Hi Alexander & rest of the experts,
The MTU size in the whole network is set to 4492. But on this router
and the router connected to it, the MTU size recommended by the
transmission team is 2000. So it's configured 2000 on this router and
1950 is configured on the router that connects to it. Can somebody
guide me how should i play with the MTU size to resolve this issue.
BGP also flaps with one of the RRs. I assume that this could also
relate to the MTU issue.

Waiting for feedback.

regards,
Adnan.
