Re: MPLS LDP IGP Sync HOLDDOWN?

What if you're using LDP autoconfiguration? You may have some links to non
MPLS enabled routers/devices, that are running a IGP (Such as a Load
balancer, firewall etc...) Without specifying a holddown time the IGP
adjacency would never come up. Although in that situation it would be best
to disable mpls entirely on those interfaces.
