Refer to the exhibit. Network 10.0.0.0/8 is being advertised to autonomous system 65550
via both external links. Which statement about the preferred path to the 10.0.0.0/8 network
is true?

A.
Router R1 will be preferred because its neighbor has the higher autonomous system
number.

B.
Router R1 will be preferred because it has the lower neighbor IP address.

C.
Router R1 will be preferred because it has a lower local preference.

D.
Router R2 will be preferred because its neighbor has a lower autonomous system
number.

E.
Router R2 will be preferred because it has the higher neighbor IP address.

F.
Router R2 will be preferred because it has a higherlocal preference.

Explanation:
Local preference is an indication to the AS about which path has preference to exit the AS
in order to reach a certain network. A path with a higher local preference is preferred more.
The default value for local preference is 100.
Unlike the weight attribute, which is only relevantto the local router, local preference is an
attribute that routers exchange in the same AS. Thelocal preference is set with the “bgp
default local-preference value” command.
In this case, both R1 & R2 learn about the network 10.0.0.0/8 but R2 has higher localpreference so R2 will be chosen as the preferred exit point from AS 65550.
