  An IOS device configured for IP+MPLS routing uses three different Maximum Transmission Unit (MTU) values: The hardware MTU configured with the mtu interface configuration command The IP MTU configured with the ip mtu interface configuration command The MPLS MTU configured with the mpls mtu interface configuration command

  The hardware MTU specifies the maximum packet length the interface can support ... or at least that's the theory behind it. In reality, longer packets can be sent (assuming the hardware interface chipset doesn't complain); therefore you can configure MPLS MTU to be larger than the interface MTU and still have a working network. Oversized packets might not be received correctly if the interface uses fixed-length buffers; platforms with scatter/gather architecture (also called particle buffers) usually survive incoming oversized packets. IP MTU is used to determine whether am IP packet forwarded through an interface has to be fragmented. It has to be lower or equal to hardware MTU (and this limitation is enforced). If it equals the HW MTU, its value does not appear in the running configuration and it tracks the changes in HW MTU. For example, if you configure ip mtu 1300 on a Serial interface, it will appear in the running configuration as long as the hardware MTU is not equal to 1300 (and will not change as the HW MTU changes). However, as soon as the mtu 1300 is configured, the ip mtu 1300 command disappears from the configuration and the IP MTU yet again tracks the HW MTU.

• Question 767:

  Which two statements about HSRP are true? (Choose two.)

  A. Its virtual MAC is 0000.0C07.Acxx.
  B. Its multicast virtual MAC is 0000.5E00.01xx.
  C. Its default configuration allows for pre-emption.
  D. It supports tracking.
  E. It supports unique virtual MAC addresses.
  A. Its virtual MAC is 0000.0C07.Acxx.
  D. It supports tracking.

  Default HSRP Configuration

  Feature

  Default Setting

  HSRP version

  Version 1

  HSRP groups

  None configured

  Standby group number

  Standby MAC address

  System assigned as: 0000.0c07.acXX, where XX is the HSRP group number Standby priority Standby delay

  0 (no delay)

  Standby track interface priority

  Standby hello time

  3 seconds

  Standby holdtime

  10 seconds

  The standby track interface configuration command ties the router hot standby priority to the availability of its interfaces and is useful for tracking interfaces that are not configured for HSRP. When a tracked interface fails, the hot standby

  priority on the device on which tracking has been configured decreases by 10. If an interface is not tracked, its state changes do not affect the hot standby priority of the configured device. For each interface configured for hot standby, you can

  configure a separate list of interfaces to be tracked. The standby track interface-priority interface configuration command specifies how much to decrement the hot standby priority when a tracked interface goes down. When the interface

  comes back up, the priority is incremented by the same amount.

• Question 770:

  Which three protocols can use enhanced object tracking? (Choose three.)

  A. HSRP
  B. Proxy-ARP
  C. VRRP
  D. GLBP
  E. NTP
  F. DHCP
  A. HSRP
  C. VRRP
  D. GLBP

  The Enhanced Object Tracking feature separates the tracking mechanism from HSRP and creates a separate standalone tracking process that can be used by other processes and HSRP. This feature allows tracking of other objects in addition to the interface line-protocol state. A client process such as HSRP, Virtual Router Redundancy Protocol (VRRP), or Gateway Load Balancing Protocol (GLBP), can register its interest in tracking objects and then be notified when the tracked object changes state.
