Which of the following combinations of LDP working modes supports LDP FRR?
Which statement describes the delay variation requirement of the voice service for the IP bearer network?
As shown in the figure, for SWA, Eth0/2 belongs to VLAN 2, and Eth0/24 (PVID = 2) is a trunk interface and permits packets from VLAN 2 and VLAN 3 to pass through; for SWB, Eth0/2 belongs to VLAN 2, Eth0/3 belongs to VLAN 3, and Eth0/24 (PVID) is a trunk interface and permits packets from VLAN 2 and VLAN 3 to pass through. Which statement is true?
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?
