As shown in the figure, RTA, RTB, and RTC use the OSPF protocol. The default cost value is used for links, and unicast routes converge on the entire network. The Loopback 0 interface is set to configure RTC as the RP or BSR. The SPT switching threshold uses the default value on RTB. The receiver joins the multicast group 225.1.1.1. The multicast source sends multicast data to the destination address 225.1.1.1. Which interface is the inbound interface in the (10.1.1.1, 225.1.1.1) entry on RTB?

The preceding are partial multicast router configurations. Which of the following configurations are required to configure the SSM Mapping on Ethernet 6/1/0 and map IGMPv2 Report messages for multicast group 225.0.0.1 to multicast source 2.2.2.2?

Which of the following statements about the merits of the HoVPN networking are true?

Exhibit:

As shown in the figure, inter-AS VPN Option A is used. CE 1 and CE 2 belong to the same VPNAS 100 and AS 200 run IGP and LDP, respectively.
ASBRs communicate with each other through EBGP. the loopback interface address of CE 1 is 10.1.1.1/24 Suppose VPNs configured on the PE and ASBR are both named vpn-1 and CE 2 can ping CE1. Which command can be ruin on ASBR 2 to find out route 10.1.1.1/24?
