  ?SoO checking: ?During the import process the SoO value in BGP update is checked against the SoO value of the site-map attached to VRF interface. The update is propagated to CE only if there is no match (this check is done regardless of protocol used on PE/CE link). ?At reception of EIGRP update, the SoO value in the EIGRP update is checked against the SoO value of site-map attached to the incoming interface. This update is accepted only if there is no match (this check can optionally be done on backdoor router).

  Ethernet Relay Service (ERS or EVPL)

  An Ethernet Virtual Circuit (EVC) is used to logically connect endpoints, but multiple EVCs could exist per single UNI. Each EVC is distinguished by 802.1q VLAN tag identification. The ERS network acts as if the Ethernet frames have crossed

  a switched network, and certain control traffic is not carried between ends of the EVC. ERS is analogous to Frame Relay where the CE-VLAN tag plays the role of a Data-Link Connection Identifier (DLCI).

  The MEF term for this service is EVPL.

• Question 810:

  Refer to the exhibit.

  

  All switches have default bridge priorities, and originate BPDUs with MAC addresses as indicated. The numbers shown are STP link metrics.

  After STP converges, you discover that traffic from switch SWG toward switch SWD takes a less optimal path. What can you do to optimize the STP tree in this switched network?

  A. Change the priority of switch SWA to a lower value than the default value.
  B. Change the priority of switch SWB to a higher value than the default value.
  C. Change the priority of switch SWG to a higher value than the default value.
  D. Change the priority of switch SWD to a lower value than the default value.
  D. Change the priority of switch SWD to a lower value than the default value.

  In this topology, we see that all port paths and priorities are the same, so the lowest MAC address will be used to determine the best STP path. From SWG, SWE will be chosen as the next switch in the path because it has a lower MAC address than SWF. From SWE, traffic will go to SWC because it has a lower MAC address, and then to SWD, instead of going from SWE directly to SWD. If we lower the priority of SWD (lower means better with STP) then traffic will be sent directly to SWD.
