As shown in the figure, the bearer network is deployed in full mesh mode. For example, RTA uses the physical interface ATM 1/0/0. The interface is devised into ATM 10/0.2 connect to RTC and RTD, respectively . The GigabiteEthernet 2/0/0 and GigabitEthernet 3/0/0 interface are used to set up a trunk as the VRRP heartbeat cable. The UMG work in active/standby mode. Media interface connected to RTA and RTB belong to VLAN 10. VRRP is enable at the VLAN interface RTA is the master router. The interface is configured as follows:
Which of the following RTA configurations are correct in VLAN 10?
A)
B)
C)
D)

문제9
As shown in the figure, the PHP function is enabled on all routers by default and an MPLS TE tunnel RT 1-RT 2-RT 3-RT 4-RT 5 is set up between RT 1 and RT 5. See the figure for label distribution of the TE tunnel. A bypass tunnel RT 2-RT 6-RT 4 is configured on RT 2 to protect RT 3. See the figure for the label distribution of the bypass tunnel. When RT 3 is faulty, RT 2 switches traffic to the bypass tunnel. How many MPLS labels do packets on the path from RT
6 to RT 4 have? What is the value of each label?
