This document describes the feature that allows the redistribution of VRF leaked BGP routes into OSPFv2 and OSPFv3.

This document describes the OSPFv2 feature that allows the setting of “Down” (DN) bit in type-5 and type-7 LSAs. The DN Bit is a loop prevention mechanism implemented when OSPF is used as CE - PE IGP protocol. Its usage in OSPF is explained by RFC4576. By default, OSPF honors the DN-bit in type-3, type-5 or type-7 LSAs in non-default VRFs.

This document describes the OSPFv2 and OSPFv3 feature that allows enabling or disabling the inclusion of LSAs having “Down” (DN) bit set in SPF calculations. The DN Bit is a loop prevention mechanism implemented when OSPF is used as CE - PE IGP protocol.

This document describes the feature that allows redistribution of DHCPv6 routes into OSPFv3. This

BFD for static routes enables monitoring of directly connected next hop reachability using a BFD session. This is
