Why each option
The default route preference value for External Border Gateway Protocol (EBGP) routes is 170 in Juniper OS.
20 is not the default preference for EBGP; it might be associated with OSPF external routes in some specific contexts.
100 is the default preference for RIP in Juniper OS, and for IBGP on Cisco, but not for EBGP on Juniper.
In Juniper OS, the default route preference value for External Border Gateway Protocol (EBGP) routes is 170. This value is used by the router to determine the preferred path when it has learned the same destination prefix from EBGP and other routing protocols.
200 is not the default preference for EBGP; it is the default for IBGP on Cisco.
