Which statement about primary VPN tunnel binding is false?
Answer : D
As shown in the figure , CE and CE 2 belong to VPN A, CE 3 and CE 4 belong to VPN B, VPN A and VPN B share the public network tunnels between border PE 1 and PE 2, and LDP tunnels are configured between PE 1 and PE 2. To isolate resources for VPN service data from PE 2 to PE 1, a unidirectional TE tunnel is configured t forward data from PE1. The QoS policy propagation though the border gateway protocol (QPPB) feature is configured on PE 2, and a QoS policy is defined when VPNs are bound to tunnel interfaces.
Which of the following statements about the configurations on PE 2 are true?
Answer : A, B, D
#
multicast routing-enable
#
interface Ethernet6/1/0
ip address 10.1.1.1 255.255.255.0
igmp timer query 40
#
igmp
The preceding are partial multicast router configurations. How long is the interval (in seconds) for
sending IGMP General Query messages when IGMP is enabled on Ethernet 6/1/0?
Answer : B
Refer to the exhibit.
As shown in the topology, RTB directly connects to RTC through the POS
interface. To implement the TE function, RTB and RTC are configured as follows:
Configuration of RTB:
