Re: Hsrp behaviour in High availibility
The base concept of A-P is both FGT config needs to be identical. Then you can't configure two ports in the same subnet between 34 and 36. Besides, without an L2 switch between the FGTs and routes, if Router1 dies while FGT1 is active the FGT1 can't get to Router2. So you need to place a switch(or cluster of switches) like LAN side.
Then LAN side, for the same reason above, you can't form one LAG/LACP split to A and P device. You have to have two LAG ports on both FGTs. Then you can split two cables from each FGT to two switches so that you have switch redundancy.
