When a large number of MAC addresses drift in the network in a short period of time, it is generally because there is a loop in the network. The Layer 2 loop can be eliminated through the STP spanning tree protocol.

To prevent attackers from forging BGP messages to attack devices, you can protect devices by configuring the GTS function to detect the range of TTL values in the IP message header. If a device is configured with "peer xxxx valid-ttl-hops 100", the valid range of TTL values of the detected messages is [155, 255].

In the network shown in the figure, R1, R2, R4, and R5 run IS-IS, and the area number is
49.0001. R3 and R6 run IS-IS, and the area number is 49.0002. Within AS 65000, R1, R3, R4, and R6 all establish IBGP neighbor relationships with R2 and R5, where R2 and R5 are RRs and R1, R4, R3, and R6 are clients. R2 and R5 also establish an IBGP neighbor relationship and configure the same Cluster ID. IBGP neighbor relationships are all established using the Loopback0 interface. The IP address of the Loopback0 interface of each device is 10.0.X.X/32, and the Router ID is 10.0.X.X, where X is the device number. R1 and R4 introduce the external network 192.168.1.0/24 into BGP through import. For 192.168.1.0/24, match based on the number of valid routes in the BGP routing table.

As shown in the IS-IS IP4 network, when the network is stable, R1 can ping 2000:12::0, and the MAC address corresponding to 2000:12::0 can be viewed through "display ipv6 neighbors".

In the IS-IS network shown in the figure, R1 introduces the default route through the "default- route-advertise always level-1" command. Which of the following descriptions are correct?
(Multiple choice)

As shown in the figure, VLAN aggregation is deployed in a switching network, where Sub-VLAN
10 and Sub-VLAN 20 are added to Super-VLAN 100. If PC1 and PC2, PC1 and PC3 are to be able to communicate with each other, which of the following descriptions about the L3 Switch interface type and the VLAN that should be allowed is correct?

The MPLS architecture consists of the control plane and forwarding plane, each of which contains multiple protocols and entries.
Which of the following tables is used to forward MPLS labeled packets?

In the OSPF network shown in the figure, the link cost value has been marked in the figure, R1 enables OSPF IP FRR, then which of the following descriptions is wrong?

A network engineer captured a multicast data frame whose destination MAC address is 01-00-5e-
00-01-01. Based on this analysis, which of the following cannot be the destination IPv4 address?

Network engineers can determine whether the link connection is normal by observing the interface indicators of the NetEngine AR6120 on site, but cannot determine whether the interface is configured with an IP address.
