Flex LSP Overview
Sticky Protect Path Info:
Flex LSP Hop Count and Cost-Max Limit
In some scenarios, path hop count is used as an estimate of path delay between a source node and destination
node.
The hop-limit is the number of nodes in the path, excluding the headend. For example, a single-hop tunnel
has a headend router and a tailend router, but no mid-node routers, a two-hop tunnel has a single mid-node
router and atailend router, and so on.
You can configure the hop-limit applicable to a specific tunnel. For example,
Router(config)# interface tunnel 1400
Router(config-if)# tunnel mpls traffic-eng path-selection hop-limit <1-255>
Consider the following simple topology with only the path cost and path hop count. The number indicated
along each link segment is the link cost.
