PR NumberSynopsisCategory: Border Gateway Protocol
1660456Incorrect inactive routes are being propagated to neighbors with add-path
Product-Group=junos
On all Junos and Junos Evolved platforms that support add-path which is used to advertise inactive external BGP routes from the VRF table, changes to that route may not be propagated. To avoid the issue please use advertise-external knob instead of add-path to advertise not best eBGP routes internally.
1669716The rpd crash is observed while making configurational changes
Product-Group=junos
On all Junos and Junos Evolved platforms, which supports protocol BGP (Border Gateway Protocol), RPD (Routing Protocol daemon) crash is seen when a eBGP peering interface is moved to a "no-forwarding" instance and resetting the BGP peer.
1671081The rpd can crash while route exchange using BGP and LDP in a rare scenario
Product-Group=junos
The rpd (routing protocol daemon) crash happens when a non-BGP (Border Gateway Protocol) route is exported via LDP (Label Distribution Protocol) and later on, if the same prefix advertised by BGP is received, we select that as the forwarded route rather than the already advertised route. This is due to the logic in the forwarding route to pick the BGP route for the BGP-owned routes rather than the active route. This is a rare case and the system recovers by itself until the next event.

Product-Group=junos
On all Junos platforms having explicit-null label along with other labels, the QoS (Quality of Service) may not work in an expected manner for AE(Aggregated Ethernet) interfaces. This is because AE interfaces do not consider the explicit-null label which carries the exp bits and thus the exp bits carried are not considered for classification by PHP (Penultimate Hop Popping) router.
