Domain VPN Tag

← All glossary terms Jump to D

Domain VPN Tag – An OSPF Type 5 LSA tag, set to a VRF's instance number, that identifies routes redistributed from a BGP/MPLS VPN so a PE router with the same VRF instance number ignores its own re-advertised routes, preventing loops for external routes.
