In this particular case, the sources are not located in the same location
hence their IP address is not adjacent to each other hence summarization is
not an option unfortunately.

I am a bit surprised if Juniper has not worked on this very limited
capacity yet even after quite some time, reason why I come to you guys to
confirm. Unfortunately I can't test it myself on my production devices
until my change window.

Appreciate if those who know could pop up and clear my doubt hence help me
save my time.
