I have to say I found this confusing and I already know what auto-export does. So by default juniper will not export routes learned locally by a PE to vrf's on that same PE even if they match the export policies. The pdf says it's split horizon type behavior, but I always thought it was because the routes were never exported into BGP so the extended communities never get applied. Whatever the reason, auto-export makes those routes eligible to be copied between VRF's local to a PE. _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
