If the ingress PE router runs an IOS®-XR version after CSCvb50266, the 5 second delay will be there by default.If the ingress PE router runs an IOS®-XR version after CSCtg68851, the 5 second delay will be there.This CDETS was created to work around the issue of CSCtg68851 Switchover from default to Data MDTs is not hitless for LC multipath Changes The 5 seconds delay was introduced on purpose due to CSCvb50266 5 Seconds MLDP forwarding delay to local receiver when there is an existing MVPN receiver Background InformationĪ Remote Receiver is a Receiver across the mLDP backbone from the point of view of the Source. This document describes a 5 seconds delay in forwarding multicast traffic over the Multipoint Label Distribution Protocol (mLDP) tree when a Remote Receiver joins the multicast Group and when the ingress PE router runs Cisco IOS ® XR.
