correct answer should be VRF, not VFP.

Correct answer is to Add a static router to the 8.8.8.8/32 destination through next hop 203.0.113.1


Ethernet 0/0 is used for the ISP1 default route.
Ethernet 0/1 is used for the ISP2 default route.


The default route named ISP1 will not come up unless 8.8.8.8 is reachable.  8.8.8.8 is not reachable without a default route.

Adding a static route to 8.8.8.8 tells the router how to reach SLA1's target so the default route can come up without the need for the other static route (ISP2).

Correct answer is to configure ebgp multihop on RB. the output of RD shows that ebgp-multihop is configured on RD.  See below example of how ebgp multihop is shown in the command output for bpg neighbors.

IOU2(config-router)#do sh run | section router bgp
router bgp 200
bgp log-neighbor-changes
neighbor 1.1.1.1 remote-as 100
IOU2(config-router)#
IOU2(config-router)#do show ip bgp neigh | inc External BGP neighbor
  External BGP neighbor not directly connected. <-- multihop not configured
  External BGP neighbor configured for connected checks (single-hop no-disable-connected-check)
IOU2(config-router)#
IOU2(config-router)#
IOU2(config-router)#neigh 1.1.1.1 ebgp-multihop 3 <-- Configure Multihop
IOU2(config-router)#
IOU2(config-router)#do show ip bgp neigh | inc External BGP neighbor
  External BGP neighbor may be up to 3 hops away. <-- output showing multihop is configured.
  External BGP neighbor NOT configured for connected checks (multi-hop no-disable-connected-check)
IOU2(config-router)#
IOU2(config-router)#
IOU2(config-router)#neigh 1.1.1.1 ebgp-multihop 10
IOU2(config-router)#do show ip bgp neigh | inc External BGP neighbor
  External BGP neighbor may be up to 10 hops away.
  External BGP neighbor NOT configured for connected checks (multi-hop no-disable-connected-check)
IOU2(config-router)#


###example once ebgp multihop is configured on opposite router.
IOU2#sh ip bgp neigh | inc remote router ID
  BGP version 4, remote router ID 1.1.1.1

remaining part of this quesiton.

After this configuration, ISP-1 and ISP-2 continue to receive the specific routes and the summary route.
Which configuration resolves the issue?

Per the link in the explanation.

"The weight is assigned locally to the router. The value only makes sense to the specific router."



"Unlike the weight attribute, which is only relevant to the local router, local preference is an attribute that routers exchange in the same AS."

Changing the weight on another router will not impact forwarding decisions made by this router.

Exhibit is wrong.

question references AS64501 exhibit uses AS100,AS200, AS300.

Exhibit is incorrect 

Table shows device id's as ASBR 2,3,4

Diagram shows ASBR 1,2,3

Who is to say the misconfiguration isn't on e0/1 of Cape Town?

The Router-ID is the tie breaker in the AS Path Selection. Path 6 wins because of its lowest Router-ID. Path 5 (RID 10.77.255.57) comes in second.

1. Weight - not a factor... no option mentions weight
2. Local Preference - Same value (100) on all paths
3. Origin Code - Same value (learned) on all paths.
4. Path Length - Same on all devices (1) an AS_Set counts as one
5. Origin ID - Same on all Devices (IGP)
6. MED - Same on all devices (0)
7. Prefer eBGP over iBGP - all paths are internal There is no distinction between Conferderation External and Confederation Internal.
8. IGP Metric - Same value (20645) on all paths.
9. Multipath - not used
10. if both paths are external, choose oldest path. not used
11. Lowest Router-ID Path 6 wins,  Path 5 is second.

Changing the Local_Pref could have the desired effect but the wording is incorrect.  Lowering the LOCAL_PREF does not select AS THE BEST PATH, you would need to raise the LOCAL_PREF for this to happen.  

Prepending the AS_PATH for the current best path would move path 6 from first to worst.  Path 5 would become the new best path.
