Exam 300-620 topic 1 question 37 discussion

I think the answer is D. Because of this stale remote endpoint, any traffic from LEAF1 toward IP2 will fail, because LEAF1 sends packets to the wrong leaf. This stale remote endpoint on LEAF1 needs to be manually cleared to resume communication. The command syntax to manually clear a particular remote IP endpoint is shown here: LEAF1# clear system internal epm endpoint key vrf <vrf-name> ip <ip-address>

I've seen couple of times wrong or stale entry on ACI which results traffic send to wrong destination leaf resulting in traffic blackholing.

D is correct: In Cisco ACI, when a stale endpoint entry exists for a destination endpoint, the fabric incorrectly assumes the stale information is valid. This results in the traffic being forwarded to the wrong destination leaf (where the endpoint was previously located). This can cause communication issues until the endpoint table is updated with the correct information through control plane updates or data plane learning.

as stated - context would indicate the switch learns it is - stale - therefore it is dropped.

I think is D

stale means stuck not there endpoint packet lost

If the traffic sourced behind L3out to an endpoint which moved to another leaf in ACI fabric, then answer is B. If traffic sourced from ACI fabric, to the endpoint which was in ACI fabric itself and now it is moved to L3out, then the Answer is D.

answer is D
