The maximum hop count of loop detection is 32 by default.
Setting the maximum hop count in path vector mode
When path vector mode is adopted for loop detection, it is also necessary to
specify the maximum value of LSP path. In this way, when one of the following
conditions is met, it is considered that a loop happens and the LSP establishment
fails.
The record of this LSR already exists in the path vector recording table.
■
The path hop count exceeds this maximum value.
■
Perform the following configuration in the system view.
Table 512 Set the maximum hop count in path vector mode
Operation

mode
Return to the default maximum hop count in
path vector mode

Displaying static LSPs
After accomplishing the configuration tasks mentioned previously, you can
execute the display command in any view to view the running state of a single or
all the static LSPs and thus to evaluate the effect of the configurations.
Table 514 Display the static LSP information
Operation
Display the static LSP information
Displaying the MPLS statistics information or LSP information of all ports
or a single VLAN interface
After finishing the configurations above, execute the display command in any
view to view the MPLS statistics information or LSP information of all ports or a
single VLAN interface. You can verify the effect of the configuration by checking
the information on display.
