Question
Refer to the exhibit. vEdge103 is connected to the headquarters using two different circuits: MPLS and Business Internet. Service VPN 100 must use only the MPLS circuit and drop the traffic when the MPLS circuit fails. Which TLOC action must be selected to enable this outcome?
Options
- AStrict
- BEqual Cost Multipath
- CPrimary
- DBackup
Explanation
To ensure Service VPN 100 exclusively uses the MPLS circuit and drops traffic upon its failure, the TLOC action must be configured as 'Strict'.
Common mistakes.
- B. Equal Cost Multipath (ECMP) distributes traffic across multiple equal-cost paths, which is contrary to the requirement of using only one specific circuit.
- C. 'Primary' typically designates a preferred path but usually allows for failover to a 'Backup' path if the primary fails, which doesn't meet the 'drop traffic' requirement.
- D. 'Backup' designates a path to be used only when a 'Primary' path fails, which is the opposite of the requirement to exclusively use one circuit and drop traffic upon its failure.
