I have one setup ....Mumbai-----Delhi with MPLS Ethernet link at both end.
My connectivity is working fine..I am able to ping Mumbai to delhi.But problem is that when i ping from Delhi to Mumbai Lotus server with load 1473....
ping 10.2.15.1 -l 1473 It getting Request Time Out.
When I ping the same IP address with load 1472 and below it work fine.
Config at Both end Router same like....
ip address 172.22.2.29 255.255.255.252
ip route-cache flow
Note: When i ping from Mumbai lotus server with load 1473 to delhi client pc..It works.
I tried follwing command, but this is maximum value.....can we configure above this value on router interface...
ip tcp adjust-mss 1460
Is it MTU problem or any?
Thanx.......Any help will appriciated in any manner......
"DF" bit indicates to the network that the packet should not be fragmented. This becomes an issue if somewhere down the path, one of the devices cannot handle the packet in its entirety and needs it to be fragmented. The "DF" bit is generally set by the source device application. In case of ping, you have to manually set it using "-f" flag. If you have not done so, that means some device down the path is not able to handle 1473 bytes and is not able to fragment as well (your host will have its MTU set at 1500, so it will not fragment the packet).
