LSP accounting statistics for single-hop LSP routes
1
Figure 20 depicts an MPLS domain for a multi-hop bypass LSP tunnel where the merge point is the
egress LER. As with the single-hop bypass LSP scenario, the statistics for the individual LSPs riding
over the multi-hop bypass LSP tunnel are accounted for. Individual LSP accounting statistics are
collected on all LSP routes riding over a single-hop or multi-hop bypass LSP tunnel even when the
merge point is the egress LER or not. For example, when there are three protected LSP routes
riding over a multi-hop bypass LSP tunnel and the merge point is the egress LER, the individual
statistics for all three protected LSP routes are collected.
