NETWORK-1182OSPF adjacency never reaches FullA link migration leaves OSPF Hellos healthy, yet LSDB exchange never completes. Community threads point back to hidden interface MTU mismatch.NetworkAdvanced24 minPro NETWORK-052BFD flaps continuouslyThe routing session looks unstable for no obvious reason, but the real break is that BFD control traffic is handled differently from the data path and gets dropped or delayed.NetworkAdvanced26 minPro NETWORK-1183BGP session comes up but no routes installA peer migration completes and BGP shows Established, but reachability never changes because the import policy still reflects the old prefix scope.NetworkAdvanced26 minPro NETWORK-059Cross-vendor redistribution loop appearsRedistribution seemed correct in each direction separately, but the combined policy creates a feedback loop because the tags used to stop reimport are not interpreted the same way everywhere.NetworkAdvanced28 minPro NETWORK-1600A BGP threshold change is right and one peer still resetsOne peer still resets after a BGP threshold change.NetworkAdvanced9 minPro NETWORK-1580A BGP max-prefix limit is updated and one peer still resetsOne BGP peer still resets after max-prefix policy updates.NetworkAdvanced10 minPro NETWORK-1610A BGP peer-group fix lands and one neighbor still shuts down updatesOne BGP neighbor still shuts down updates after a peer-group fix.NetworkAdvanced10 minPro NETWORK-1552A BGP policy update lands and one Arista neighbor still leaks the retired communityOnly one neighbor leaks a retired community after BGP policy cleanup.NetworkIntermediate10 minPro NETWORK-1590A route-policy rename is complete and one BGP peer still resetsOne BGP peer still resets after a route-policy rename.NetworkAdvanced10 minPro NETWORK-1592An EVPN import cleanup is correct and one leaf still imports the old routeOne leaf still imports the old EVPN route after cleanup.NetworkAdvanced10 minPro NETWORK-1602An EVPN import policy is fixed and one leaf still learns the wrong routeOne leaf still learns the wrong route after an EVPN policy fix.NetworkAdvanced10 minPro NETWORK-1582An EVPN route-target cleanup is correct and one leaf still imports the old routeOne EVPN leaf still imports the old route after cleanup.NetworkAdvanced10 minPro NETWORK-1570An IDS mirror source is corrected and one sensor still sees the wrong VLANOne IDS sensor still sees the wrong VLAN after SPAN cleanup.NetworkAdvanced10 minPro NETWORK-1572An MLAG peer template is updated and one VLAN still lands wrongOne VLAN lands wrong after MLAG template cleanup.NetworkAdvanced10 minPro NETWORK-1557A NetFlow exporter migrates and one collector still attributes traffic to the old zoneTraffic is misattributed only after a NetFlow exporter restart and migration.NetworkAdvanced11 minPro NETWORK-1562An EVPN import policy is updated and one leaf still learns the old route-targetOne EVPN leaf keeps learning a retired route-target after policy updates.NetworkAdvanced11 minPro NETWORK-1491An OSPF adjacency reaches ExStart and resetsAn OSPF adjacency flaps only after failover on a firewall cluster sitting between routers.NetworkAdvanced11 minPro NETWORK-1501An OSPF adjacency reaches ExStart and resetsOSPF flaps only after firewall failover between two routed segments.NetworkAdvanced11 minPro NETWORK-1511An OSPF failover looks clean and adjacency still resetsOSPF flaps only after a firewall cluster failover between routed segments.NetworkAdvanced11 minPro NETWORK-1531An OSPF failover looks clean and adjacency still resetsOSPF flaps only after a firewall cluster failover.NetworkAdvanced11 minPro
