According to the configuration shown in the figure below, you can know that R4 has an interface advertised into IS-IS?
In an MPLS network, functions such as neighbor discovery, session establishment and maintenance, and label management are implemented by exchanging LDP messages between SRs running the DP protocol. To ensure the reliability of message delivery, all LDP messages are sent and received based on TCP connections.
As shown in the figure, an engineer uses 4 routers to test branch network interoperability. Among them, R1, R2, and R3 in branch 1 deploy OSPF to implement network interoperability. R2, R3, and R4 in branch 2 deploy IS-S to implement network interoperability. Now the engineer wants to implement R1 to access the loopback interface address of R4. Which of the following operations can meet this requirement?
BGP routing policies can control the advertisement and reception of routes.
In BGP/MPLS IP VPN, the 0SPF multi-instance process uses the DN bit to prevent Type5 LSA loops.
As shown in the figure, MPLS LSP is set up in the network, and the goal is to establish an LDP session between SWA and SWB.
Regarding the description of the encapsulation format of labels in MPLS, the correct one is
Regarding multi-instance CE (Mlulti-VPN-Instance CE, MCE), which of the following descriptions is wrong?
The traditional BGP 4 can only manage IPv4 single routing information. In order to provide support for a variety of network layer protocols, MP-BGP extends BGP-4. MP-BGP uses address families to distinguish different network layer protocols. Which of the following address families are currently supported?

ping -a Xc Ys z -vpn-instance M 10.5.16.2, the meaning of this command is:
In the multi-level RR scenario, a large number of secondary RRs will be connected to the primary RR, which may lead to BGP of the primary RR. The routing table overflows, what method can be used to reduce the risk of overflowing the routing table of the advanced RR BGP?
Which of the following is included in the routine collection of basic equipment information?
In the process of viewing the debug output through the SSH terminal, a lot of information pops up. Which of the following operations can
Make the Moni tor terminal no longer pop up debug messages?
As shown in the figure, OSPF is enabled on all interfaces of the router, and the ip address identified in the figure is the device's IP address.

In the DU label distribution mode, if the Liberal retention mode is adopted, the device will retain the labels distributed by all LDP peers, regardless of whether the LDP peer is the optimal next hop to the destination network segment.
In an MPLS VPN network, data packets are forwarded when they enter the public network. will be encapsulated with two layers of MPLS labels

A campus has deployed IPv6 for service testing. There are 4 routers (R1, 22, R3 and R4) in this network, running 0SPFV3 to realize the interconnection of IPv6 network. A new router R5 needs to be connected to the network for testing. An engineer introduces a direct route in the OSPFVV3 process of R4 so that devices in the campus network can access the GE0/0/1 port address of R5. Which of the following statements about the scene is true of?

In intra-domain MPLS VPN networks, data packets will be encapsulated with two layers of MPLS when they enter the public network and are forwarded.
