From this figure, it can be known that
About the difference between NSR and NSF, which is correct?
If faced with a complex network failure, and it is estimated that the troubleshooting cannot be completed in a short period of time, and the user urgently needs to restore the availability of the network, then the correct approach is.
Which of the following statements about LDP Label Retention - Free Way is true:
In the absence of a header, the Domain ID of each OSPF process running on the router and the process ID of the process
Be consistent and can be modified under the process through the domain-id command
From this figure, we can conclude that
In an operator's MPLSVPN network, there are two devices PE1 and PE2 for MPLSVPN data forwarding. PE1 receives a private network route of 172.16.1.0/24 from the client, and converts it to a VPNv4 route on PE1 and assigns a label of 1027 Released to PE2. The outgoing label of the MPLS LSR-ID of PE2 reaching PE1 is 1025o When a client on PE2 accesses 172.16.1.0/24, the frame sent by PE2, the inner and outer labels should be a combination of the following 6 options?
A campus has deployed IPv6 for service testing. In the early stage of deployment, engineers wanted to achieve network interoperability through IPv6 static routes. When creating an IPv6 static route. You can specify both the outbound interface and the next hop, or only the outbound interface or only the next hop.
As shown below:
(Multiple Choice) Which LSAs in OSPFv3 can be flooded in an area?
When configuring the DHCP Relay function on the device, the VLAN ANIF interface of the relay connection client must be bound with a DHCP server group, and the IP address of the proxy DHCP server must be configured in the bound DHCP server group.
As shown in the figure, Sitel and Site2 need to achieve mutual access through the operator's BGP/MPLS IPVPN. A known
The public network tunnel between PE1 and PE2 has been established (the label information is shown in the figure), and PF1 has
The 192.168.1.0/24 network segment route is advertised to PE2 through the MP.JIBGP neighbor relationship, and the route learning is normal. When grabbing between P and PE1, when Site2 accesses the 192.168.1.0/24 data of Sitel, the outermost label
What should the sign be?
FEC In/Out label
1.1.1.1/32 6662/3
Configuring DHCP Snooping can be used to prevent imitator attacks, so the configuration process needs to include the following
What are the steps?
After the cutover acceptance is completeD. what work still needs to be performed in the closing stage?
In BGPIMPLS IP VPN, if the OSPF protocol is used between PEs and CEs to exchange routing information, the domain identifier (Domain ID) is used to distinguish whether the incoming routes in the VPI instance come from the same OSPF domain.
What is the purpose of configuring LSP fragmentation on an IS-IS device?
The configuration shown is performed on R2 to filter all incoming routes. Suppose there is a BGP route with the AS_Path attribute of [100200300400] on R1 that needs to be sent to R2. Please help the network administrator to adjust the AS order in the AS_Path attribute of the route on R1 to ensure that the route entry will not be filtered by the routing policy of R2____, ____, ____, ____.
100 This space corresponds to the [A] space in the routing policy
200 This space corresponds to the [B] space in the routing policy
300 This space corresponds to the [C] space in the routing policy
400 This space corresponds to the [D] space in the routing policy
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.
Loopback0 presses the IP address of the port, RI, R2, R3EJLoopbacD is advertised in the area 1, R4
