The BGP Cisco ACI must be configured to reject route advertisements from BGP peers that do not list their autonomous system (AS) number as the first AS in the AS_PATH attribute.
Description
Discussion Text
Verifying the path a route has traversed will ensure the IP core is not used as a transit network for unauthorized or possibly even internet traffic. All autonomous system boundary routers (ASBRs) must ensure updates received from eBGP peers list their AS number as the first AS in the AS_PATH attribute.
An alternative to route maps is to use subnets under the External EPG with the correct route Controls assigned as discussed in vendor documentation (Reference the L3 out white paper).
