In a network where there is an active router and a backup router, one connected to the active ISP router and the other connected to the back ISP router, can I advertise the same routes to the ISP routers?

Is it possible to advertise internal subnets to both the active ISP router and the backup ISP router in a topology like the following:

[Active SRX] -------Active ISP

192.168.10.0/24 ----[SWITCH]

[Backup SRX] ------Backup ISP

In this case it is indeed possible for both the active SRX and backup SRX to advertise the 192.168.10.0/24 route over BGP to the Active ISP router and Backup ISP router at the same time and it shouldn't cause any issues however please double check the upstream routing with the ISP and make sure this will have no impact, please refer to https://www.juniper.net/documentation/us/en/software/junos/bgp/topics/task/routing-protocol-bgp-security-configuring.html on how to configure BGP.
