Question 572

Refer to the exhibit. Which configuration resolves the route filtering issue on R1 to redistribute all the routes except 172.16.2.48/28?

    Correct Answer: C

    The correct option to resolve the route filtering issue on R1 to redistribute all the routes except 172.16.2.48/28 is C. This is because the configuration uses 'match route-type external', which matches all external routes regardless of their type (type-1 or type-2). Options A and B specifically target OSPF external type-1 and type-2 routes, which might not encompass all the external routes in this context. Option D mentions 'level-2', which pertains to IS-IS routes and is irrelevant here. Thus, option C is the most appropriate as it ensures that all external routes except the mentioned one are redistributed.

Type 1 and 2 with ospf

dapardoOption: C

I decided to lab this question and Im going with C. I was typing the command and external option will be the most appropiate (by selecting this we are choosing all the external routes). R7(config-route-map)#match route-type external ? 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) type-1 OSPF external type 1 route type-2 OSPF external type 2 route <cr>

agree with C

To add, this question is of bad quality as it is not actually solving the issue correctly. Ideally you just not redistribute any static route into OSPF, as this seems the only one being redistributed. Also if you want to do something with matching ONE route, you can better match on the actual network using "match ip address ..."

DefiletOption: C

Should be C . External type 1 & 2 are for OSPF R5(config)#router eigrp 1 R5(config-router)#redistribute ospf 1 match ? external Redistribute OSPF external routes internal Redistribute OSPF internal routes nssa-external Redistribute OSPF NSSA external routes

Bombbear_WOption: C

I pick C Because the figure clearly tells 172.16.2.48/28 are outside EIGRP routes, unless its' wrong. The type-1 and type-2 in A & B mean OSPF external type 1 and external type 2.
