Hi all,
Trying to understand where, why and how to properly use the above command.
The command reference says,
"neighbor allowas-in
To configure provider edge (PE) routers to allow readvertisement of all
prefixes containing duplicate autonomous system numbers (ASNs), use the
neighbor allowas-in command in router configuration mode. To disable the
readvertisement of the ASN of the PE router, use the no form of this
command.
neighbor allowas-in number
no neighbor allowas-in number"
Could somebody explain what that's saying in plain English. And, maybe
describe a scenario where using this command makes sense. I'm confused
because the only that I know of where there would be deplicate ASN's is when
ASn's have been prepended and I know this command isn't needed then.
Also, is this command only applicable when MPLS is somehow involved in the
config? Or, might this command be needed in the type of BGP scenarios
possible in the lab?
Thanks in advance
