Limiting the Number of Hops the LSP Can Traverse

To limit CSPF to choosing a path consisting of no more than 20 hops for LSP tunnel1, complete the following steps.

Enable the device for configuration.
```
device# configure
```
Enable the MPLS router.
```
device(config)# router mpls
```
Enable and configure the label switched path (LSP).
```
device(config-router-mpls)# lsp tunnel1
```
In this example, the selected LSP is named tunnel1 .
Configure the limit number of hop the LSP can traverse.
```
device(config-router-mpls-lsp-tunnel1)# hop-limit 20
```
In this example the hop-limit is set to 20.

the following example limits the CSPF to choosing a path of no more than 20 hops for LSP tunnel1.

device# configure terminal
device(config)# router mpls
device(config-router-mpls)# lsp tunnel1
device(config-router-mpls-lsp-tunnel1)# hop-limit 20
