  • The MPLS router must be configured to synchronize IGP and LDP to minimize packet loss when an IGP adjacency is established prior to LDP peers completing label exchange.

    &lt;VulnDiscussion&gt;Packet loss can occur when an IGP adjacency is established and the router begins forwarding packets using the new adjacency b...
