A. both routers R1 and R2

B. router R1

B. On PE routers, the CE IBGP neighbors are configured in the global BGP configuration

C. On PE routers, the CE EBGP neighbors are configured in the VRF context

D. A separate BGP process must be used on the PE routers for CE routers so that they do not use the same BGP routing process as that used for the PE router‘s other provider neighbors

B. Only remote routers are configured as stubs.

C. Stub routers are not queried for routes.

D. Spoke routers connected to hub routers answer the route queries for the stub router.
