Click the Exhibit button. Both configuration hierarchies shown in the exhibit have been committed to your MX Series device. Which two statements are true in this scenario? (Choose two.)
A.
Traffic destined to 10.3.0.1 will use the R1-to-R6 LSP as a next hop
B.
Traffic destined to 10.3.0.1 will not use the R1-to-R6 LSP as a next hop
C.
The active 10.3.0.0/24 prefix installed in the route table will have a route preference of 5
D.
The active 10.3.0.0/24 prefix installed in the route table will have a route preference of 7
A -> route will use because static route is using it as next next hop
C -> RSVP route preference is 7, comparing to static route preference 5 -> it will use static route
Answer A C
root@AT# run show route 10.3.0.0
inet.0: 30 destinations, 36 routes (30 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both
10.3.0.0/24 *[Static/5] 09:21:27
> to 198.51.100.1 via ge-0/0/1.0, label-switched-path AT-to-DA
[RSVP/7/1] 00:00:15, metric 11
> to 198.51.100.1 via ge-0/0/1.0, label-switched-path AT-to-DA
A & C are correct.
[edit]
root@R1# show routing-options
static {
route 10.0.0.3/32 {
lsp-next-hop TO_R3;
}
}
router-id 10.0.0.1;
[edit]
root@R1# run show route 10.0.0.3
inet.0: 9 destinations, 10 routes (9 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both
10.0.0.3/32 *[Static/5] 00:05:12
> to 172.16.0.2 via ge-0/0/1.0, label-switched-path TO_R3
Static route with next-hop is an LSP has the preference of 5.
The answer should be A & C:
MPLS Default preference: 5 for static MPLS LSPs, 7 for RSVP MPLS LSPs, 9 for LDP MPLS LSPs
https://www.juniper.net/documentation/us/en/software/junos/mpls/topics/ref/statement/preference-edit-protocols-mpls.html
StaticLSP preference is 6. So the best answer should be (The active 10.3.0.0/24 prefix installed in the route table will have a route preference of 6). Hence, A and C is correct answer.
Answer should be AC. install <dst> active will be discovered via RSVP with pref 7 while static route <dst> lsp-next-hop R1-to-R6 will be installed as a static route with pref 5.
Active knob just tell us that the route learned from RSVP should be installed in inet.o rather than inet.3, but the preference remain 7 and therefore the route learned via static which has preference of 5 will be selected for forwarding.
