Release Information
Statement introduced in Junos OS Release 9.6.
Description
Enable load balancing for multiple label-switched paths (LSPs).
Options
lsp-equal-cost | — | Configure LSPs to be retained as equal cost paths for load balancing when a better route metric is added to the routing table. When a route with an improved metric is added to the IS-IS internal routing table, IS-IS flushes all next-hop information (including LSP next-hop information) for a route. This is undesirable, because certain equal-cost multipath (ECMP) path combinations can be lost during route calculation. To override this default IS-IS behavior, include the lsp-equal-cost statement for load balancing, so that the equal cost path information is retained in the routing table. |
