Host Address FEC vs. Address Prefix FEC From RFC 3036: An Address Prefix FEC element which is a full address (a /32) has a different effect than a Host Address FEC element which has the same address. A packet may match two LSPs, one with a Host Address FEC element and one with an Address Prefix FEC element. In this case, the packet is always assigned to the former. A packet which does not match a particular Host Address FEC element may not be sent on the corresponding LSP, even if the Host Address FEC element identifies the packet's egress router. This IS allowed on a /32 Address Prefix FEC that matches the egress router. |
