Hi, group:
ring1-------R1<---dlsw--->R2----ethernet
I always see (lf 1500) in the dlsw remote-peer command from cisco's example and
ccie power session. But when read the design guide of the dlsw, I think it's n
ot neccesary, at least for the TCP encapsulation. Could anyone make this clear
for me?
The following is from the design guide: http://www.cisco.com/warp/public/cc/pd/
ibsw/ibdlsw/prodlit/dlsw4_rg.htm
In general, when using TCP encapsulation, you probably will not need to change
the largest frame size because TCP
fragments the frame size according to the MTU. For example, if the LF is smalle
r than the MTU, then TCP will fragment each packet and send them in sections ac
ross the WAN. If the LF is larger than the MTU, then individual packets will be
placed into the TCP/IP frame.
