This command will generate a default-route in L2 database.
.. cfgcmd:: set protocols isis ldp-sync
This command will enable IGP-LDP synchronization globally for ISIS. This
requires for LDP to be functional. This is described in :rfc:`5443`. By
default all interfaces operational in IS-IS are enabled for synchronization.
Loopbacks are exempt.
.. cfgcmd:: set protocols isis ldp-sync holddown <seconds>
This command will change the hold down value globally for IGP-LDP
synchronization during convergence/interface flap events.

This command disables Three-Way Handshake for P2P adjacencies which
