B. ge-0/1/0, ge-0/0/2, ae0, ae1

C. ge-0/0/1, ge-0/1/1, ae0, ae1

You are asked to advertise the 1.0.0.0/8 and 1.5.5.5/32 routes to your 10.254.32.2 BGP peer.

Referring to the exhibit, which configuration change would satisfy this requirement?

Referring to the exhibit, you have EBGP peerings with both ISP1 and ISP2. You are receiving the 172.25.12.0/24, 172.25.13.0/24, 172.25.14.0/24, and 172.25.15.0/24 routes through both neighbors. You must ensure that traffic to these prefixes are load balanced through both service providers. You have configured a load-balancing policy and have applied it to the forwarding table, but the prefixes are not being load balanced.

What is required to accomplish this task?

A. The multihop feature should be enabled between both neighbors.

B. The multipath multiple-as feature should be used between both neighbors.

C. The as-override feature should be used between both neighbors.

D. The include-mp-next-hop feature should be used between both neighbors.

A customer requires that the switch responds to an ARP request only if the source and target IP address are on different subnets.

Referring to the Exhibit, how would you accomplish this task?

A. Create a static ARP entry for the host.

B. Enable the no-gratuitous-arp request command under the interface hierarchy.

You want to implement an RP in your PIM sparse mode environment, you are considering the advantages and disadvantages of the various RP election methods.

In this scenario, which three implementation guidelines are correct? (Choose three.)

A. The auto-RP method requires using two PIM dense mode groups from the 232/8 range.

B. The auto-RP method includes the ability to maintain a backup RP.

C. With the bootstrap method, the primary criterion for electing a BSR is priority value.

D. When multiple election methods are implemented on a device, the static method is preferred.

E. The static method requires configuration on all devices in the PIM domain.

You are attempting to configure BGP peering to a new service provider. The BGP peering state is stuck in the active state.

What are two reasons for this happening? (Choose two.)

A. The local autonomous system number is not configure
