I have a scenario where I have an EX4300 that needs to have redundant links to an MX204 router. My initial thought was to setup LAG with LACP, but I am wondering if this is possible or not. I couldn't find any documentation for setting up LAG between a switch and a router. Then I was thinking maybe VRRP was a better solution. I'm just looking for input from more experienced engineers because I don't have a lot of experience with either of these two applications other than some testing labs a few years ago.
Perhaps there is a better way I'm unaware of, also. What I am trying to accomplish is to have fiber trunks on the EX4300, ports xe-0/2/0 and xe-0/2/1 connected to an MX204 on xe-1/1/0 and xe-1/1/1 respectively, act as one logical link with a gateway IP address configured on the router's two interfaces (or one logical interface). Load balancing would be nice, but it's not necessary.
