Question 11

Regarding the mpLS handling mode of TTL, is the following description correct?

Pipe mode. When an IP message passes through the MPLS network, the IPTTL minus 1 is mapped to the WLSTTL field at the incoming node.

The TTL in the B. MPLS label has the same meaning as the TTL field in the head. TTL prevents mpLS networks from developing bad routing.

Unifore style, when an IP packet passes through the MPLS network, the IPTTL of the incoming node is minus l. The MPLS TTL field is a fixed value.

In MPLSVPI, if you need to hide the structure of the MPLS backbone network, you can use Uniform mode on Ingress for private network messages .

Question 19

The correct description of configuring BGP4+ is that

BGP4+ does not support route reflectors.

The next hop of a B. BGP4 route can use the Link-Local address.

BGP4 configures the reflector, the role positioning of the reflector and the client needs to be consistent with the configuration of BGP4

BGP4 specifies p

Question 20

A company network runs the OSPF protocol, a project in order to understand the OSPF mechanism in the network to perform packet transfer operations, the following description of ospf messages is correct?

The interface sends a Hello packet immediately after joining the OSPF region

LS update packet is sent only when the adjacency relationship is established

When an LsUpdate packet is received, the router must send an LsAck acknowledgment
