Filtering Routes by IP Address with Prefix List

You need to reject all routes to certain IP addresses because you don't want to install them into the routing table.

Create a list of all the IP address prefixes:

# set policy-options prefix-list PREFIX-LIST-1 10.0.0.1/24
# set policy-options prefix-list 
PREFIX-LIST-1 10.10.0.0/16

# show
prefix-list PREFIX-LIST-1 {
     10.0.0.1/24;
     10.10.0.0/16;
}


Then create a policy that references the list of prefixes:

# set policy options policy-statement Addresses-to-Reject term 1 from prefix-list PREFIX-LIST-1
# set policy options policy-statement Addresses-to-Reject term 1 then reject
[Here the policy name is Address-to-Reject and I make this policy as reject, if you want to accept this policy then type accept.]

Finally, apply the policy to a protocol, here I use EBGP:

# set protocols bgp group external-group import Addresses-to-Reject
