Alcatel-Lucent NRS II – Frame Relay and ATM Services — Question 11

Which of the following statements is TRUE concerning the advertisement of VRF routes on a 7750 SR?

Answer options

• A. By default, a 7750 SR does not advertise all routes in the VRF to a CE router.
• B. The default 7750 SR behavior describes all routes in a VRF that are advertised to other PE routers.
• C. By default, a 7750 SR does not advertise all routes in the VRF to other PE routers.
• D. By default, a 7750 SR advertises all routes in the VRF to a CE router.

Correct answer: A, B

Explanation

The correct statement is A, as by default, a 7750 SR does not advertise all VRF routes to CE routers. Option B is incorrect because the default behavior does not imply that all routes are advertised to other PE routers; it only indicates a selective advertisement. Options C and D are also incorrect as they misrepresent the default behavior of route advertisement in terms of PE routers and CE routers.
