The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
ospf timer ldp-sync hold-max-cost { value | infinite }
The interval for advertising the maximum cost in the LSAs of local LSRs through
OSPF is set.
By default, the value of the hold-max-cost timer is 10 seconds.
You can choose different parameters as required.
– When OSPF carries only LDP services, to ensure that the route selected by OSPF
is always the same as the LDP LSP, infinite must be specified.
– When OSPF carries multiple services including LDP services, to ensure that OSPF
route selection and other services still run normally if the LDP session of the
primary LSP fails, value can be specified.
If this command is issued repeatedly, the latest configuration takes effect.
When IS-IS runs as an IGP, perform the following steps on the interfaces of both ends of
the link between the crossing node of active and standby links and the LDP neighboring
