5.6 6.0

Description (partial)

Node dynamic bypass (link /node) LSP.

1)	In multi-vendor environment:

Problem : Calculating <ActualPathHop> when a path involves non ALU nodes ( which is not managed by SAM) is not possible.
	If a hop is to non ALU node than we will not be able to iterate and resolve the hop.

Solution: Log an error saying path has non ALU node and such LSP will not have corresponding entries in <ActualPathHop> table.

2)	As you know technically ISIS and OSPF can be enabled in the network ( node)  and MPLS is protocol independent, 
what if a LSP path is taken via a node where it is on an interface running ISIS protocol and MC is run with OSPF protocol.
Is it expected that <ActualPathHop> be populated ? Since as of now path resolution is only for IGP interfaces know to MC

Solution: Log an error saying path has interface which is not part of protocol used by MC  and such LSP will not have corresponding entries in <ActualPathHop> table.

Symptom:
<ActualPathHop> table will not have hop involving multi-vendor nodes

Conditions:
There is bypass LSP with hop having mult-vendor nodes.
