[j-nsp] Stripping off BGP Prepends

[Paul Stewart]

Thanks for the replies....

I follow what you're saying Phil but that's "ugly".. no offense ;)  We're
going to fire this back to the customer and tell them there's nothing we can
do I think.... we try our best to be "hands off" when it comes to customer
traffic involving BGP (except for typical filters etc of course).

There are some other uses though for this feature - I'm figuring if RAS
hasn't gotten this from Juniper in 10 years I'm wasting time even thinking
about it...;)

Paul

How about bloking their bgp route and instead redist'ing an aggregate
with a configured AS-Path. Not exactly the same but similar in the end
