I think there are some other aspects why such a approach is required. In a DC,

If we use TTL, at least we could say the path between ingress and egress node
is OK if OAM is OK. Because the OAM packet goes through exactly the same
forwarding behavior

How is it ensured that incrementing the udp source port (outer header encap)
will detect ALL ecmp paths ?

TTL use is fine and it works with existing hardware, but what this document is
trying to provide another alternate approach where all devices are OAM capable
and can look at O bit.

I agree. You should use TTL. TTL use will also solve layer violation issue.

If TTL works then why invent a new method. Also this draft is very different

How does a node know it should copy these packet to CPU?
Is it by looking inside the packet without terminating the outer layer? Why not
use TTL expiry?

Hi guys,
In the draft, it says:
Each network device receives the Path Tracking packet from its upstream device,
makes a copy of it and passes the copy to its CPU.
