This is controlled via local configuration. </pre> </div></div> <p>Currently it is possible to prepend only one instance of own AS to the path.  </p> BGPCEP-1014

Improvement High Confirmed Unresolved Unassigned Grzegorz Sulek pick-next pt Sat, 20 Aug 2022 10:55:16 +0000 Wed, 24 Jan 2024 15:54:31 +0000 0.21.0 0.19.9 0.20.7 BGP 0 2 <p>This has a tie-in with policies, as expressed in openconfig-rp-statement. That bit of code seems to do the right thing, assuming there are multiple actions are present.</p> <p>As a first step, I think we need some upfront design as to how this should work &#8211; either an explicit feature, or a policy thing.</p> <p>The other consequence of this is that path selection needs to treat the same ASN appearing consecutively in an AS_SEQUENCE is a single AS, not as an AS loop &#8211; otherwise we would end up disqualifying it rather than proceeding to check the AS distance.</p> Development Rank 0|i042w7:
