Hi,We are going to improve our current network by adding additional switch, router and firewall in order to eliminate single point of failure. Below is the network topology (also as attached), but I am not quite sure on the design especially on the redundant trunk group between routers and switches. Appreciate if you guys could give some comments on it. Secondly, does J-Series router support LACP? Our internet router is using Cisco 2960 and will connect to 2xJ6350 routers using LACP.
May be you can try and make the EX3200 as 2 member VC and enable no split detection, so that atleast one member stays UP in case of any issue. This will eliminate the need for RTG.
Yes J-Series router supports LACP. Refer page 6 of https://kb.juniper.net/library/CUSTOMERSERVICE/technotes/3500133-EN.pdf
