Hey guys,
troubleshooting routing issues on paths external to our network that lead to blackholing of specific 5-tuple combinations here, very likely due to ECMP/Bundling issues (we are link is up/up and used for load-balancing, but cannot actually transmit or receive traffic, therefor dropping those packets on the floor). Now, this happened a few times over the years, and I am wondering if you guys have any suggestions or tools that you use in those cases, other than tcpdump'ing at both ends, generating thousands of 5-tuple combinations and then analyzing them in wireshark. Also, after obtaining a list of affected and unaffected 5-tuples, any particular easy way to find out how this is getting hashed, so that we could find the likely number of bundle members (this could be very useful multiple interconnection and parties are involved).
