Refer to the Cisco IOS-XR configuration exhibit. The Cisco IOS-XR router is unable to establish any PIM neighbor relationships. What is wrong with the configuration?

A. The configuration is missing:
interface gi0/0/0/0
ip pim sparse-mode
interface gi0/0/0/1
ip pim sparse-mode
interface loopback0
ip pim sparse-mode

B. The RP address has not been configured using the rp-address router PIM configuration command

C. PIM defaults to dense mode operations only, so PIM sparse mode must be enabled using the pim sparse-mode router PIM configuration command

D. The configuration is missing:
multicast-routing
address-family ipv4
interface gi0/0/0/0
enable
interface gi0/0/0/1
enable

E. The auto-rp scoping configurations should be set to 1 not 16

Referring to the topology diagram show in the exhibit, which three statements are correct regarding the BGP routing updates?

A. The IBGP routing updates received by R3 from R2 will be propagated to the R6 router.

B. The IBGP routing updates received by R1 from R4 will be propagated to the R5, R7, and R2 routers.

C. The IBGP routing updates received by R2 from R1 will be propagated to the R3 router.

D. The EBGP routing updates received by R1 from R5 will be propagated to the R2, R4, and R7 routers.

E. The EBGP routing updates received by R3 from R6 will be propagated to the R2 and R4 routers.

F. The EBGP routing updates received by R1 from R5 will be propagated to the R2 and R4 routers.

When a BGP route reflector receives an IBGP update from a non-client IBGP peer, the route reflector will then forward the IBGP updates to which other router(s)?

A. To the EBGP peers and other clients and non-clients.

B. To the other clients only.

C. To the EBGP peers only.

D. To the EBGP peers and other clients only.
