Re: [j-nsp] VC ports on EX4300

VC port carries inter switch traffic (potentially large) and also some state replication traffic. (not very much) The answer mostly depends on how much your inter-switch traffic are. On Tue, Feb 14, 2017 at 3:17 AM, Valentini, Lucio wrote: > Hi there, > > I was

I used ex4200 to do exactly what you did before. ex4200 releases is pretty rock solid, feature extensive, although with lower arp entry limits. Given the price difference maybe you can connect each l2 domain to its own ex4200 and have them do ospf routing among selves, which maybe give you

Would someone help to create one? reducing TCP-MSS is really just a compare write on a fixed location in IP header, should be a simple enough operation., but without it half the world doesn't work quite right with tunnels (GRE tunnels on ex)., due to malfunctioning pmtu, so we kind of stuck with

Does EX4200 support changing TCP-MSS on transit packets? I'm trying to use ex4200 as a simply gateway, and I need to lower tcp-mss on outgoing packets since the return path maybe tunneled. This seems to be a simple enough per-packet filtering operation, does EX switch support this? Cheers.
