Abstract
A static label-switched path (LSP) over which packets belonging to a forwarding equivalency class (FEC) are forwarded may be tested by (a) generating a multi-protocol label switching (MPLS) echo request message including a target FEC stack type-length-value (TLV), the target FEC stack TLV having a Nil FEC sub-TLV; and (b) sending the MPLS echo request message with a label stack corresponding to the FEC for forwarding over the static LSP. A static segment routed traffic engineered (SRTE) path, including at least two segments, over which packets belonging to a forwarding equivalency class (FEC) are forwarded, may be tested by (a) generating a multi-protocol label switching (MPLS) echo request message including, for each of the at least two segments, a target FEC stack type-length-value (TLV), each target FEC stack TLV having a Nil FEC sub-TLV; and (b) sending the MPLS echo request message with a label stack corresponding to the FEC for forwarding over the static SRTE path.
