Which two methods can you use to limit the range for EIGRP queries? (Choose two.)

The correct answer is C. Summarize routes at the boundary routers of the EIGRP domain. E. Configure stub routers in the EIGRP domain.. This question asks for two methods to limit the propagation scope of EIGRP queries, which are sent when a route becomes unavailable to find an alternate path.

Question

Which two methods can you use to limit the range for EIGRP queries? (Choose two.)

Options

  • AUse an access list to deny the multicast address 224.0.0.1 outbound from select EIGRP neighbor
  • BConfigure route tagging for all EIGRP routes.
  • CSummarize routes at the boundary routers of the EIGRP domain.
  • DConfigure unicast EIGRP on all routers in the EIGRP domain.
  • EConfigure stub routers in the EIGRP domain.
  • FUse an access list to deny the multicast address 224.0.0.10 outbound from select EIGRP

Why each option

This question asks for two methods to limit the propagation scope of EIGRP queries, which are sent when a route becomes unavailable to find an alternate path.

AUse an access list to deny the multicast address 224.0.0.1 outbound from select EIGRP neighbor

Denying 224.0.0.1 (all hosts multicast) would disrupt other network functions and is not specific to EIGRP queries, which use 224.0.0.10.

BConfigure route tagging for all EIGRP routes.

Route tagging is used for policy control and filtering, not directly for limiting the scope of EIGRP query propagation.

CSummarize routes at the boundary routers of the EIGRP domain.Correct

Summarizing routes at boundary routers prevents EIGRP queries from propagating beyond the summarization point, as the summary route provides a valid path, stopping the query from seeking more specific routes in the summarized direction.

DConfigure unicast EIGRP on all routers in the EIGRP domain.

While EIGRP can use unicast, merely configuring unicast neighbors does not inherently stop query propagation across the entire domain without additional mechanisms like summarization or stub routing.

EConfigure stub routers in the EIGRP domain.Correct

Configuring a router as an EIGRP stub router limits its participation in the EIGRP network by preventing it from propagating queries from other routers, effectively containing queries within its connected segment.

FUse an access list to deny the multicast address 224.0.0.10 outbound from select EIGRP

Denying 224.0.0.10 (EIGRP multicast address) outbound would prevent EIGRP from forming neighbor relationships and exchanging routing information entirely, not just limiting queries.
