So how do one force iBGP sessions to choose a larger datagram size? Do
you have to do it in the BGP config with 'neighbor a.b.c.d transport
path-mtu-discovery' or is there a more automatic solution?

'ip tcp path-mtu-discovery' global command or the one You mentioned
for per-neighbor tuning.

I set 'ip tcp path-mtu-discovery' on all my boxes by default, and the vast majority of them still assumed 516 or 536 MSS. I tweaked the transport options in a few routers and that brought up the MSS. It looks like the code on one of ME6524s won't let me set that option though so I guess an upgrade is in order.

Thanks
