Refer to the Exhibit.
Referring to the exhibit, your network contains eight devices participating in OSPF Area 0, and
they are all in a full IBGP mesh. R7 is learning the 172.27.0.0/24 network and is injecting this
route into OSPF and BGP. You must ensure that on R2, all traffic destined to the 172.27.0.0/24
network from R1 uses the R2-to-R7 RSVP LSP through your core network.
How should you accomplish this behavior?
A.
Use the install active feature on R2.
B.
Use the install feature on R2.
C.
Use OSPF and BGP import policies on R2.
D.
Use OSPF and BGP export policies on R2.
Explanation:
answer – A.
install active places prefiks to inet.0

May be install active places prefixes in inet.3 table not inet.0

“install” feature places prefixes in inet.3 table, which is used by BGP only.
“install active” feature places prefixes in inet.0 table, which is used by the IGPs.
From the above question, since the learnt route is advertised into OSPF and BGP, and the OSPF route is going to be the active route in inet.0 (better route preference), “install active” should be used to ensure the LSP will be the next hop for that route.
