Hi list,

I thought I had read something about that but cannot find the pointers
anymore:

Does the Cisco default-configuration check in BGP inbound announcements,
if the first ASN of the AS path is the ASN which is configured as
"neighbor ... remote-as"?

Example, is the following check built-in the BGP code and therefore not
needed to configure:

"""
router bgp 65001
 neighbor 129.168.1.1 remote as 65002
 ...
 neighbor 129.168.1.1 filter-list 1 in
!
ip as-path access-list 1 permit ^65002_
ip as-path access-list 1 deny .*
"""

If so, at some exchange-points there are route-servers which strip their
own ASN out of the path.  How would one configure such a setup from the
client side?

Thanks in advance,
-tim
