Hi, Keep in mind that SRX and MX/MPC use different command hierarchy for the load balancing hash config, which means your lab will not be useful.
SRX (and MX/DPC) use "hash-key" MX/MPC use "enhanced-hash-key" The hash is used on the ingress card of the MX (which might not be the card connected to you 3750). http://kb.juniper.net/InfoCenter/index?page=content&id=KB24339 http://www.junosandme.net/article-junos-load-balancing-part-1-introduction-105738134.html -----Original Message----- From: juniper-nsp [mailto:juniper-nsp-boun...@puck.nether.net] On Behalf Of Keith Sent: Tuesday, September 24, 2013 1:38 AM To: juniper-nsp@puck.nether.net Subject: [j-nsp] LACP/LAG Between MX and Cisco Hi. We have a 3750X and an MX480 connected together. As the gig link between the two is now approaching capacity we will be turning up a LAG between the two. As the traffic is all coming in from the internet through the MX towards the 3750 and customer eyeballs, I'm wondering on the 'best' way to load balance that traffic coming from the MX to the 3750. I have things in my lab going, but there are lots of load-balancing options on the 3750 and the juniper (srx240) in my lab does not have the same options as the MX we use. In reading and experimenting, I get different results in my lab but as there are more options on MX than the srx, I am unsure of what load-balancing options would work best in this scenario. Using a vlan on the cisco with an IP address, connecting two ports in an channel and connecting both ports to the MX, and have an IP address on ae0.
