Cisco ENCOR Routing Protocols 3

Question 1

When redistributing external routes into EIGRP, which metric components must be specified?

Accepted Answer

Bandwidth, delay, reliability, load, and MTU

Answer

Redistributing into EIGRP requires all five metric components (bandwidth, delay, reliability, load, MTU) to be defined via `default-metric` or inline, since EIGRP has no default for external sources.

Question 2

Which command displays OSPF neighbor adjacency states and identifies the DR/BDR on each segment?

Accepted Answer

show ip ospf neighbor

Answer

`show ip ospf neighbor` lists all OSPF neighbors, their adjacency states (Full, 2WAY, etc.), dead timers, and their DR/BDR roles on each network segment.

Question 3

Which OSPF router type and command is used to perform inter-area route summarization?

Accepted Answer

ABR using `area range`

Answer

Inter-area summarization in OSPF is configured on ABRs with the `area range` command, which aggregates Type 3 Summary LSAs sent between areas.

Question 4

Which BGP attribute is advertised to eBGP neighbors to influence which entry point into your AS neighboring ASes should use?

Accepted Answer

MED (Multi-Exit Discriminator)

Answer

MED is sent to external BGP neighbors to suggest a preferred entry point into your AS; lower MED values are preferred and it is the primary tool for influencing inbound traffic from adjacent ASes.

Question 5

In EIGRP, what occurs when a router loses its Successor and no Feasible Successor exists in the topology table?

Accepted Answer

It enters Active state and sends QUERY messages to all neighbors

Answer

When no Feasible Successor exists, EIGRP transitions the route to Active state and sends QUERY messages to all neighbors seeking an alternative path to the destination.
