We do have a multi home scenario and makes sense to only advertise your
network.

 

Thanks

It depends. Do you have a multi-home scenario and therefore you peer with
another AS?

If so, probably you don't want to become a transit AS, show you should
permit out only your AS (_1234$)

Otherwise redistribute your network into bgp, summarize it or install the
prefixes you have with network command.

someone correct me please if I am wrong.

that's correct..

test it using show ip bgp regex _1234$ (where 1234 is the AS where routes
are originated)

Hi,

Just checking to make this is the correct command to make sure I only get
the ISP originated routes

ip as-path access-list 1 permit _1234$

Thanks
