Exhibit:
The figure shows the typically mode in which a common softswitch access the bearer network. VRRP is enabled on RTA and RTB. In normal cases, RTA is the VRRP master router and RTB is the VRRP is the VRRP salve router. The ETH_trunk is enabled between RTA RTB. IF VRRP is not bounded to BFD and each [parameter uses their default settings, which statement is the true when the upstream link of RTA is faulty?
Exhibit.
As shown in the figure, external route 1.1.1.0/24 is imported to RTA that is located in the NSSA area RTD is a
backbone area router. RTB and RTC are both area border router (ABRs). OSPF configuration are as follows.
Which statement is true?

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?
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:
