IPv4 In-Band Management

IPv6 Routing

IPv4 Multicast Routing

IPv6 Multicast Routing

All of the above are MT topologies defined for IS-IS.

The router sends a copy of the LSP from its database to its neighbor

The router updates its database with the LSP and floods a copy to its other neighbors.

The router updates its database with the LSP, acknowledges the LSP with a PSNP and floods a copy to its other neighbors.

The router updates its database with the LSP and acknowledges it with a PSNP.

RIPv1, RIPv2, and BGP are distance vector protocols.

OSPF and IS-IS are distance vector protocols.

Routing tables are exchanged between neighbors; however, no routing table is transmitted beyond the immediate neighbor.

Distance vector protocols use the Dijkstra SPF algorithm.

Routers that participate in distance vector routing protocols maintain full knowledge of distant routers and how they interconnect

Not So Stubby Areas

Level 1 Areas

Stub Areas

Partially Stubby Areas

In multi-access networks, a DR and BDR are elected only if there are more than two routers connected to the network segment.

In multi-access networks, a DR and BDR are elected only if the subnet masks on the router interfaces are less than /30

In multi-access networks, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.

In multi-access networks, a DR and BDR are elected. The DR sends link-state advertisements describing the network.

The prefix list reject should be "192.168.3.0/16 exact".

Router R1 should be configured as an OSPF "asbr".

The policy "reject" should be set for import rather than export.

The policy was likely not "committed" after creation.

This is not possible because OSPF cannot use import policies.

The system ID

The loopback address

The sequence number of the hello packet

The device that first initiated communication becomes the DIS

One.

One for each of the routers in area 0

One for each of the external routes exported by router R1.

Type 4 LSAs are not generated in this network topology.

Full; both routers are exchanging Helios to maintain the adjacency.

The adjacency is down.

The adjacency is in exstart state.

The adjacency is in the exchange state.

Area ID W B.

Hello and Dead intervals PC.

Stub flag

Checksum values

The list of neighbors

The router with router ID 10.10.10.5 is an ASBR.

The router with router ID 10.10.10.3 is an ASBR.

The router with router ID 10.10.10.5 originated the AS summary LSA in its own area.

The router with router ID 10.10.10.4 is in the same area as the router with router ID 10.10.10.5.

IPv6 uses the Address Resolution Protocol to resolve the address to a MAC address.

A Neighbor Discovery message is sent to the broadcast MAC address. The host with the IPv6 address responds with a Neighbor Advertisement message.

A Neighbor Discovery message is sent to the solicited-node multicast address. The host with the IPv6 address responds with a Neighbor Advertisement message.

A Neighbor Discovery message is sent to the anycast address for the LAN. The host with the IPv6 address responds with a Neighbor Advertisement message.

IPv6 addresses do not need to be resolved to a MAC address.

The link state information is not populated in the database but is forwarded to all neighbors

The link state information already in the database is overwritten and the age is reset

The link state information is not populated in the database and an acknowledgement is sent

The link state information is regarded as old and nothing is done.

Router R1

Router R2

Routers R1 and R2

Router R4

The age for newly created link state information is set to 0 for OSPF and 1200 for IS-IS

The age for newly created link state information is set to 1200 for OSPF and 0 for IS-IS

The age is incremented or decremented as it is flooded from router to router and as it is held in the topological database.

The age is incremented or decremented only as it is held in the topological database and not as it is flooded router to router.

224.0.0.5

224.0.0.6

The unicast IP address of the interface the update is being sent on.

The system address of the router

The router sends a copy of the LSP from its database to its neighbor

The router sends a PSNP to its neighbor describing the LSP in its database.

The router updates its database with the LSP and floods a copy to its other neighbors.

The router sends a PSNP to its neighbor to request the LSP.

An OSPF type 3 LSA is an intra-area LSA, generated by the ABR only when route summarization is configured.

An OSPF type 3 LSA is an inter-area LSA, generated by the ABR only when route summarization is configured.

An OSPF type 3 LSA is an inter-area LSA, generated by an ASBR to describe external routes.

An OSPF type 3 LSA is an inter-area LSA, generated by the ABR to describe a route to neighbors outside the area.
