Sample BGP topology redundancy

We have a sample topology as below. On AS4000 side, there is a PC goes to R1 and some IPs behind the R1. vSRX1 and R1 routers have 2 WAN connection between them. We name upper one as line 1 and lower one is line 2. vSRX1 receives routes of 8.8.8.0/23 and 12.12.12.0/24 through line…
