The destination IP address of the LDP Discovery message is the multicast IP address

224.0.0.2

The LDP Discovery message is sent to the specified LDP peer

The LSR does not does not send Hello messages any longer after TCP connections

are established

The LDP Discovery message is encapsulated into a UDP packet and its destination port number is 646

TRUE

FALSE

Virtual link can solve the problem that backbone areas are logically non-contiguous.

A virtual link can be established between any two ABRs, but the two routers must have interface that are connected to the same non backbone area. routers must have interfaces that are connected to the same

A virtual link unnecessarily belongs to the backbone area, Instead, which area It belongs to depends on the actual topology.

A virtual link belongs to Area 0.

TRUE

FALSE

AS-external-LSAs can be advertised within a stub area

AS external route can only be based on a default route that is manually configured on an

ABR.

A virtual link cannot pass through a stub area

Any area can be a stub area

RSTP defines the edge port role. The edge port does not receive and process configuration BPDUs, and not participate in RSTP calculation

When the root port fails, the optimal alternate port will become the root port and the forwarding state.

In RSTP, when a port is elected as the designated port, it enters the discarding state.

Then the port immediately enters the forwarding state

In RSTP, when a port receives is bpdus form the upstream designated bridge , the port will compare the own stored is bpdu with the E. When the designated port fails, the optimal alternate port will become the root port and enter the forwarding state.

BGP uses TCP as the transport protocol.

BGP uses the same algorithm as RIP, namely, distant

BGP uses the TCP port 179.
