This object specifies how many times the local BGP autonomous system number is permitted to appear in the AS-path of VPN routes received by this VRF, which is otherwise rejected by default as a loop-prevention measure. It's relevant only when the VRF's virtual router is configured with an ASN and BGP is enabled. For example, in a hub-and-spoke VPN topology where routes legitimately traverse the same AS twice, an administrator might set this to 2 to allow those routes to be accepted instead of dropped as apparent loops.
