Is that any ways to add in HSRP on R1, R2 & R7. Because if R2 router connection to R1 download, the standby will take over here. I can't seem to add properly nor know how to actullay use HSRP at all

When I try add in loopback address on R6, i will lost connection of pinging PC Enrg to PC Sale If i add in on R6

network 6.6.6.6 0.0.0.0 area 0
