SRX 340 both routers as Master- no advertisement received
[ Edited ]
I have been experiencing strange issue with Juniper SRX 340 using firmware 15.1X49-D70.3. Vrrp is setup on both routers but advertisements "sent" not received on both routers. host-inbound services are allowed and both interfaces are in correct zones. Both routers remain Masters and won't show backup router ip when show vrrp is done. However for a split of a second secondary router changes state to Backup (when intially setup) and then back to Master and remain Master .
whislt troubleshooting i have downgraded fimrware to 15.1X49-D45 (i knew this works previously) and everything work as normal. I don't want to use this firmware as its old therfore please can someone advise.
