Exhibit.

RTA is an edge route of the MPLS backbone network. It provides the access for users under layer 2 switches and differentiates user by subinterface. User access VALN 100 and has subscribed to the His ViIP , and services. According to 802 1p priorities, the value 0 indicates the HIS service, 1 indicates the VoIp service and 4 indicate the IPTV service. The DiffSerc model is deployed in E-LSP mode on the MPLS network,

And the STC is configured for subinterface on the access side of RTA (the qos phb disable command is not configured). Outgoing on the traffic on the G1/0/0.1 suninterface involves the His VoIP, and services on the access side of RTA. Which statements about EXP about values corresponding to these three services is true?

As shown in the figure, IGP is configured on RT 1 and RT 2, and route 193.3.6.0/24 is configured on RT 2. Which of the following statements is correct? Suppose OSPF is used here. Configure an access control list (ACL) on RT 2 in system mode.

ACL 2000

rule 5 permit source 193.3.6.0 0.0.0.255

Configure a routing policy in system mode:

route-policy t permit node 1

if-match acl 2000

apply backup-nexthop 106.108.4.1

apply backup-interface Ethernet4/0/4

Configure the IP FRR in system mode:

ip frr route-policy tConfigure the ethe4/0/4 interface of RT 2:

ospf cost 100

Configure BFD on RT 2:

Enable BFD on Ethernet4/0/3

bfd b1 bind peer-ip 106.108.3.1 interface Ethernet4/0/3

discriminator local 1

discriminator remote 1

min-tx-interval 10

Configuration on RT 1:

Enable BFD on Ethernet7/0/3

bfd b1 bind peer-ip 106.108.3.2 interface Ethernet7/0/3
