If the user changes the value of the LDP synchronization timer parameter, the new value will take
effect at the next synchronization event. In other words, if the timer is still running, it will continue
using the previous value.
If parallel links exist to the same neighbor, then the bindings and services should remain UP as long
as there is one interface that is UP. However, the user configured LDP synchronization timer still
applies on the failed then restored interface. In this case, the 7450 will only consider this interface for
forwarding after IGP re-advertized its actual cost value.
Note that the LDP Sync Timer State is not always synched across to the standby CPM, so after an
activity switch the timer state might not be same as it was on the previous active CPM.
The no form of this command disables IGP/LDP synchronization and deletes the configuration
Default
no ldp-sync-timer
Parameters
seconds — Specifies the time interval for the IGP-LDP synchronization timer in seconds.
loopback
Syntax [no] loopback
Context config>router>interface
Description This command configures the interface as a loopback interface.
Default Not enabled
lsr-load-balancing
Syntax lsr-load-balancing hashing-algorithm
no lsr-load-balancing
Context config>router>if
Description
This command specifies whether the IP header is used in the LAG and ECMP LSR hashing
algorithm. This is the per interface setting.
Default
no lsr-load-balancing
Parameters
lbl-only — Only the label is used in the hashing algorithm.
lbl-ip — The IP header is included in the hashing algorithm.
ip-only — the IP header is used exclusively in the hashing algorithm
mac
Syntax mac ieee-mac-addr
no mac
