• Question 359:

  A network administrator is creating an OMP feature template from the vManage GUI to be applied to WAN edge routers. Which configuration attribute will avoid the redistribution of the routes back into the OMP from the LAN side?

  A. configure "Number of Paths Advertised per Prefix"

  B. configure "Overlay AS Number"

  C. configure "Send Backup Paths"

  D. configure "ECMP limit"

  Correct Answer: B

  By default, OMP is transparent to BGP even if propagate-aspath is configured. overlay-as is a feature that prepends AS specified as a parameter of this command to the BGP AS_PATH attribute of routes exported from OMP to BGP. If you configure the same overlay AS number on multiple devices in the overlay network, all these devices are considered to be part of the same AS. As a result, they do not forward any routes that contain the overlay AS number, hence the routing loop is prevented.

• Question 360:

  A. valid

  B. backup

  C. active

  D. staging

  Correct Answer: D
