implemented today), or reduce MTU at both sides.
As this is a L2 link, you can't use things like MSS adjust etc...

We're considering using EoMPLS port mode to bridge two datacenters
together temporarily for a move using sup720-3BXL on both ends with 6724
blades, probably 2 or 4 gig links, possibly 10g if I can get them to buy
the HW. The question I have primarily is with regard to MTU. I have
heard there

From a routing perspective this makes sense. Will there be any adverse
effects if the Jumbo frames is bumped up anywhere in the chain? Meaning L2
vs. the L3 Routing. I believe thats where the MTU path discovery comes into
play correct? Sorry to add to this but while we were on the subject I

The other nice thing about SEC is that it can handle a busy log server

On new builds I prefer to run cabling to each rack and use 65xx (not the

Why not nail up a separate GRE tunnel between the two spokes and let the

Actually that shows the 850 as 5.12mb/s with 64 byte packets, not
ipsec. I know it offloads, but I don't know how much it really can do.
They show the 1841 as 38.4mb/s so that might be the safe way to go since
I already have one.

You might look at Sawmill as well, has user level access controls to

That would help cpu, can find them on ebay cheap. The 28xx would be the
way to go, however. We replaced our 3620s with 2811s and they run
circles around the old 3620s, built in ipsec acceleration not to mention
boatloads more ram and cpu (and not on the verge of EoL).
