I have a few customers' customers, who appear at a local IX. Due
to the MLPA-like nature of the IX, I hear their prefixes both at
the IX and via my own transit customers. I normally use localpref
to prefer customer advertisements over peers' advertisements.
There is a customer's customer who is advertising more-specifics at
the IX (and using a different source AS, to boot). I can think of
a couple ways to prevent hearing these, but thought I should ask
for suggestions first.
you should honor your customers routing policy and simply accept the
routes.
Whilst it is nice to accept a downstream of a downstream's routing
policy like that I don't think it is your place to say that. The other
response asking what the problem is also is a good example of the
misunderstanding of problems with the shim6 solution although at a
different place in the network. If MY policy is to send all customer
traffic through my customer connections, I should be able to do that.
To answer the OP's question I'd be looking at manually filtering the
more specifics if they are also sending the aggregates through the IX.
