Refer to the Exhibit.
Router 2 is receiving a route to 10.0.0.0/8 from Router 4 and Router 5. What will Router 2 do with
the routes shown in the exhibit?
A.
Router 2 will mark both routes active if both next hops are reachable.
B.
Router 2 will prefer the route received from Router 4 because of a lower origin code value.
C.
Router 2 will prefer the route that arrived first because neither route is necessarily preferable
over the other.
D.
Router 2 will prefer the route received from Router 5 because it has a lower MED value.
The Origin Attribute
0. BGP assigns an IGP route a value of 0
1. BGP assigns an EGP route a value of 1
2. BGP assigns unknown routes a value of 2
Based on the exhibit, the origin attribute is not explicitly listed. As both links are EGP routes, the origin value of both routes is 1.
Therefore, the correct answer is D.
0
0
At the end of AS Path You can see I and E so
Router 2 will prefer the route received from Router 4
Example:
Route received:
20.0.0.0/24 *[BGP/170] 00:03:03, localpref 100
AS path: 65000 E
> to 10.0.0.1 via fe-1/3/0.0
