Correct me if I am wrong, but I don't think _54_ would work because "_"
matches ^ or $ as well. Which means this would match something like
"100 54"
I would say it should be something like 54(_[0-9])+

Hi,
well it depends from where you look from.
When you'r in AS54, outside means not originated locally
ip as-path access-list 1 deny ^$
When your in AS100 directly connected to AS54 and you get the path:
54
54 200 300
That means the path should not end with 54. So there must be
something else
after 54 also. So then i would say:
ip as-path access-list 1 permit _54_.
would also work.
By the way, could you tell me what's the path from the DocCD to the
regex? :)
