I have setup a simple network where we have BGP running between WAN port and ISP . We are learning default route from ISP and advertising all 10 routes to ISP .
The problem I am experiencing is for single subnet 172.22.234.0/24 that I am leaning from another BGP neighbor connected on a LAN port. I am able to successfully reach this subnet and traceroute also takes me to that but customer who is on a different local subnet is unable to reach that 172.22.234.0/24 . Customer's trace is stopping at my Juniper router.
There are two things that I want to implement
1) logging how do I enable traffic log to/from a source to destination to see if there is any hit on Juniper and whether its stopping it? Do I just create a local file and enable all traffic logs please can someone advise.
2) How do I troubleshoot this further as my trace is reaching that subnet fine
Trace from Juniper
