NEW QUESTION # 38
Refer to the exhibit.
When the FastEthemet0/1 goes down, the route to 172.29.0 0/16 via 192.168.253 2 is not installed in the RIB. Which action resolves the issue?
- A. Configure feasible distance greater than the successor's feasible distance.
- B. Configure feasible distance greater than the reported distance
- C. Configure reported distance greater than the feasible distance
- D. Configure reported distance greater than the successor's feasible distance.
Answer: B
Explanation:
From the exhibit, we notice network 172.29.0.0/16 was learned via two routes:
+ From 192.168.254.2 with FD = 307200 and AD = 281600
+ From 192.168.253.2 with FD = 410200 and AD = 352300
The first route is installed into the RIB as the successor route because of lower FD.
When the first route fails, router will not use the second route as it does not satisfy the feasibility condition. The feasibility condition states that, the Advertised Distance (AD, also called the reported distance) of a route must be lower than the feasible distance of the current successor route.
NEW QUESTION # 39
Drag and drop the packet types from the left onto the correct descriptions on the right.
Answer:
Explanation:
Explanation
Unlike legacy network technologies such as ISDN, Frame Relay, and ATM that defined separate data and control channels, IP carries all packets within a single pipe. Thus, IP network devices such as routers and switches must be able to distinguish between data plane, control plane, and management plane packets to treat each packet appropriately.From an IP traffic plane perspective, packets may be divided into four distinct, logical groups:1. Data plane packets - End-station, user-generated packets that are always forwarded by network devices to other end-station devices. From the perspective of the network device, data plane packets always have a transit destination IP address and can be handled by normal, destination IP address-based forwarding processes.2. Control plane packets - Network device generated or received packets that are used for the creation and operation of the network itself. From the perspective of the network device, control plane packets always have a receive destination IP address and are handled by the CPU in the network device route processor. Examples include protocols such as ARP, BGP, OSPF, and other protocols that glue the network together.3. Management plane packets - Network device generated or received packets, or management station generated or received packets that are used to manage the network. From the perspective of the network device, management plane packets always have a receive destination IP address and are handled by the CPU in the network device route processor. Examples include protocols such as Telnet, Secure Shell (SSH), TFTP, SNMP, FTP, NTP, and other protocols used to manage the device and/or network.4. Services plane packets - A special case of data plane packets, services plane packets are also user-generated packets that are also forwarded by network devices to other end-station devices, but that require high-touch handling by the network device (above and beyond normal, destination IP address-based forwarding) to forward the packet. Examples of high-touch handling include such functions as GRE encapsulation, QoS, MPLS VPNs, and SSL/IPsec encryption/decryption, etc. From the perspective of the network device, services plane packets may have a transit destination IP address, or may have a receive destination IP address (for example, in the case of a VPN tunnel endpoint).
