Refer to the exhibit. An engineer must troubleshoot a connectivity issue impacting the redistribution of the subnet 172.16.2.48/28 into the OSPF domain. Which configuration on router R1 advertises this subnet into the OSPF domain?
A.
R1(config)#route-map CCNP permit 10 R1(config-route-map)#match tag 200
Answer is A
An engineer must troubleshoot a connectivity issue impacting the redistribution of the subnet 172.16.2.48/28
Look exhibit R4 has NO routes because EIGRP is NOT being redistributed. We want to redistribute 172.16.2.48
Look at the R4 static route with a tag of 200.
A = Correct
B would be correct if 172.16.2.48 was an external route on R2 as well as R4. This way it has no tag and gets redistributed.
C is for redistributing from ospf not from EIGRP
D is for redistributing from IS-IS not EIGRP
A == wrong as it is unlikely the EIGRP external route is tagged with 200, if not, the 172.16.2.48/28 will not be redistributed. Please note non-tagged routes are dropped due to implict deny in a route-map
B == seems correct implies tagging redistributed route with tag 200, so only routes without a tag of 200 will be redistributed
C == wrong, as it matches "route-type internal", the route "172.16.2.48/28" == external type (eigrp: D EX)
D == wrong, as it matches "route-type level-2" and this is only required when using IS-IS level-2 routes == not applicable here
WAN(config-route-map)#match route-type ?
external external route (BGP, EIGRP and OSPF type 1/2)
internal internal route (including OSPF intra/inter area)
level-1 IS-IS level-1 route
level-2 IS-IS level-2 route
local locally generated route
nssa-external nssa-external route (OSPF type 1/2)
Actually, the EIGRP external route is tagged with a tag of 200. See the route-map of R4 in the exhibit. Correct answer is A
route-map CCNP permit 10
match ip address 10
set tag 200
access-list 10 permit 172.16.2.48 0.0.0.15
Answer is A
An engineer must troubleshoot a connectivity issue impacting the redistribution of the subnet 172.16.2.48/28
Look exhibit R4 has NO routes because EIGRP is NOT being redistributed. We want to redistribute 172.16.2.48
Look at the R4 static route with a tag of 200.
A = Correct
B would be correct if 172.16.2.48 was an external route on R2 as well as R4. This way it has no tag and gets redistributed.
C is for redistributing from ospf not from EIGRP
D is for redistributing from IS-IS not EIGRP
B defeat the purpose of the question, the question is requesting to advertise the 172.16.2.48/28 subnet to the ospf.
that's why the correct answer is A
