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

I have resolved the session hanging issue by lowering the MTU value to
1920 on this router. But the BGP session is now flapping a lot and
it's flapping with both the RRs now. Should I try the tcp-mss option
or should i further play with the MTU value. I lowered the value to
1800 but the flapping

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.

Do you have MPCs in the MX240? I have seen similiar issues,
which had been caused by software bugs - if so, try restarting
the linecards and do the software update. Some small packets
go through but bigger ones are sometimes dropped...

Hi Experts,
I have a MX240 router installed at a remote location. I am able to
telnet/SSH the router but when I run a command that needs to return a
large output (e.g. show log messages or show conf) the session hangs
and then I have to re-establish the connection. Because of this I
couldn't
