OSPF includes type 1 and type 2 external routes

The cost of a Type 1 external route is the addition of the AS external cost and the AS internal cost the cost form a router to an A

The cost of a Type 2 external route is the AS external cost

A Type 2 external route is always preferred over a Type 1 external route when other when other conditions are the same

On a PIM-SM network multicast routers that have just started need to send Hello messages to discover neighbors and maintain neighbor relationships

Multicast routers periodically send Hello Messages to each other to maintain communication

A DR is selected on a network segment based on Hello messages exchanged between routers

Hello messages are sent to multicast group address

Multiple users can be created for network management Users may be asked to log in to

eSight from specified IP addresses in specific time ranges.

% The administrator can force unauthorized login users to log out.

% The login time of the administrator role also can be limited.

MSTP is configured incorrectly

A physical link alternates between up and Down triggering the device to send a large number of TC packets

The MSTP-enabled device receives MSTP TC packets that are transparently sent or from the client

The priority of the port in the specified MSTL is not configured

After a router receives a Network-Summary-LSA, this router runs a SPF algorithm.

Network-LSA describes link state information of broadcast and NBMA segment.

A virtual connection is a virtual link that belongs to the backbone area (Area 0).

Type 4 LSA describes how to reach an A5BR, including routing and topology information.

When the edge node finds a new destination address in its routing table that does not belong to any existing FEC the edge bode not crate

An LSP is established by binding an FEC to a label and advertising the binding relationship to the neighboring LSR

lf the egress node has available labels for distribution it allocates labels for the FEC and sends a label mapping message to the upstream node

After receiving a label mapping message the LSR adds the corresponding entry to the label forwarding table
