Exam 300-415 topic 1 question 220 discussion

One thing is to have many paths in your routing information base (that's how many is sending to you the vsmart = send-path-limit), other one to have them installed in your routing table. for me is ecmp-limit 2 equal cost multi path. If all the parameters are equals for a route then both are installed, it should send the traffic by default through both paths. Is what i think. Thanks and good luck to all of you. OMP Send-Path-Limit is a configuration parameter that defines the maximum number of equal-cost vroutes that a vSmart controller or a vEdge router advertises to its OMP peers the number of routes that get installed in the routing tables is subject to another OMP parameter called ecmp-limit.

Not sure which one is correct but I've found this: The send-path-limit parameter defines the maximum number of best-paths that can be advertised. The ecmp-limit parameter defines the maximum number of best paths that can be installed in the routing table.

Option B, omp no shutdown send-path-limit 2, is not correct because the send-path-limit parameter controls the number of equal-cost routes that a vEdge router advertises to its neighbors, not the number of routes that it installs in its own FIB. The send-path-limit parameter is primarily used to reduce the amount of routing information that is exchanged between vEdge routers. By limiting the number of routes that are advertised, the network can reduce the amount of bandwidth that is consumed by routing updates.

Agree, it has to be A

the number of routes that get installed in the routing tables is subject to another OMP parameter called ecmp-limit. so I believe correct is A

A is the correct answer

IMO it's A If you want to route traffic (which means to send packets on a different links), you need to use ecmp-limit, because it affects the data plane. The question does not mention advertising prefixes (which is configured with send-path-limit). Send-path-limit would advertise two prefixes to vSmart and it would pass them to other EDGEs, so they could load balance, but only if they have ecmp-limit >= 2.

send-path-limit Configure the maximum number of equal-cost routes that are advertised per prefix (on vSmart controllers and vEdge routers only). It should be B. https://www.cisco.com/c/en/us/td/docs/routers/sdwan/command/sdwan-cr-book/config-cmd.html#r_send_path_limit_3834.xml
