Our WISP network has been running OSPF/MPLS for quite a few years now, but we always seem to have issues with MPLS labels dropping between certain sites after a brief outage.
Today we had a power issue on one of our sites, and it caused the MPLS labels to not re-establish between a few of our sites in our network, including ones that were not the impacted site by the power outage.
This issue will be fixed by disabling and enabling the LDP interface on the affected sites that are dropping labels between them.
Any thoughts as to why this is?
Our tower site routers will have a /30 on a Vlan between them, advertised on Area backbone.
We have MPLS interfaces (dummy bridge) with an IP address on them that will also be advertised on OSPF.
Adding the Vlans as the LDP interfaces. - These are the interfaces we will need to disable/enable in order to get our labels back, along with the tunnels.
Another thing we have tried, is to add the MPLS interface to the LDP interfaces itself, and then statically adding the LDP neighbors (neighboring MPLS IP addresses), which works, but doesn't appear to fix this issue in particular.
Anyone else have issues with dropped labels on MPLS?
