NETWORK-282A route-reflector keeps the primary path while the backup path attributes are never re-advertised after policy cleanup during a failover rehearsalReachability remains while fast failover assumptions quietly disappear. Normal traffic masked the issue until the standby or alternate path became active under rehearsal conditions.NetworkAdvanced18 minPro NETWORK-162A standby edge keeps routes while losing the preference signal that made inbound traffic behave correctly during a failover rehearsalFailover succeeds functionally and inbound policy intent disappears on the alternate path. Normal traffic masked the issue until the standby or alternate path became active under rehearsal conditions.NetworkAdvanced18 minPro NETWORK-511A static summary route is valid (Rollout Stuck)A static summary route is valid (Rollout Stuck) focuses on Routing And Failover Paths and asks the reader to isolate Rollout Stuck in Cisco. 실무에서는 rollout-stuck 이슈를 볼 때 DNS, 라우팅, ACL/방화벽, 목적지 응답을 계층별로 잘라서 확인하면 장애 구간을 훨씬 빠르게 좁힐 수 있습니다.NetworkIntermediate18 minPro NETWORK-105A VXLAN VTEP loopback is reachable in the default table but not in the transport VRF and overlays stay downPing tests look fine from one context, yet the actual encapsulation source resides in a different VRF that lacks the same reachability.NetworkAdvanced18 minPro NETWORK-192An engineered path exists while forwarding never actually prefers it during a failover rehearsalThe control-plane setup is visible and the data-plane choice remains unchanged. Normal traffic masked the issue until the standby or alternate path became active under rehearsal conditions.NetworkAdvanced18 minPro NETWORK-149An EVPN anycast gateway MAC is correct on both leaves, but one site keeps an older virtual router MAC and hosts split traffic unpredictably after maintenanceGateway abstraction exists, yet endpoint behavior diverges because one site's virtual identity is stale.NetworkAdvanced18 minPro NETWORK-156An EVPN border leaf imports the route target correctly, but export policy blocks the MAC-IP advertisement toward the legacy MPLS edge and hybrid reachability failsThe new fabric side looks fine, yet the interdomain bridge is missing one critical advertisement direction.NetworkAdvanced18 minPro NETWORK-387An EVPN fabric imports the tenant route-targetAn EVPN fabric imports the tenant route-target focuses on wan-and-overlay-connectivity and asks the reader to isolate Rollout Stuck in Cisco. 실무에서는 rollout-stuck 이슈를 볼 때 DNS, 라우팅, ACL/방화벽, 목적지 응답을 계층별로 잘라서 확인하면 장애 구간을 훨씬 빠르게 좁힐 수 있습니다.NetworkAdvanced18 minPro NETWORK-124An EVPN fabric imports type-5 routes but misses the companion type-2 host signals, so specific reachability breaks while summaries look fineOverlay routing seems healthy at a prefix level, yet endpoint-level forwarding fails because one route family is absent.NetworkAdvanced18 minPro NETWORK-180An overlay fabric can flood traffic broadly while one endpoint optimization still trusts stale host identity during a failover rehearsalGeneral connectivity looks healthy and one endpoint remains blackholed due to stale local knowledge. Normal traffic masked the issue until the standby or alternate path became active under rehearsal conditions.NetworkAdvanced18 minPro NETWORK-104BGP add-path is enabled on the route reflector, but the edge still rejects the extra routes due to a capability mismatchThe core advertises multiple paths, yet the edge keeps only one because one side never negotiated the additional-path capability correctly.NetworkAdvanced18 minPro NETWORK-091BGP community is set on ingress but removed by a route-map sequence later in the same policy chainThe intended tag exists briefly, yet traffic engineering never works because a later policy step strips it before export.NetworkAdvanced18 minPro NETWORK-135EVPN ARP suppression keeps the old IP-to-MAC entry after a DHCP reassignment, and east-west peers blackhole the hostAddress reuse looks safe on the DHCP server, yet the overlay still trusts an earlier endpoint identity.NetworkAdvanced18 minPro NETWORK-132GRE keepalives remain up, but an underlay ACL blocks the recursive route to the tunnel destination during WAN failoverTunnel health appears good until the underlay path changes, exposing a missing control route allowance.NetworkAdvanced18 minPro NETWORK-108LDP sessions form, but labels stay withheldMPLS control adjacencies look normal, yet forwarding never starts because the platform still considers the underlay unstable.NetworkAdvanced18 minPro NETWORK-076Policy-based routing sends health-check probes into a blackhole next hopNormal application flows look fine, but the service stays unhealthy because policy routing treats the health-check source differently and steers it to a dead path.NetworkAdvanced18 minPro NETWORK-097Route reflector client to client reflection is disabled and one site never learns the backup exit pathThe RR is reachable, yet backup routes are missing because the reflection policy does not actually propagate client routes to the other client set.NetworkAdvanced18 minPro NETWORK-126The MLAG peer link looks healthy, but orphan port behavior prevents storage VLAN failover the way the team expectedRedundant links exist, yet one edge case in dual-chassis behavior leaves a subset of single-homed devices isolated.NetworkAdvanced18 minPro NETWORK-117Tunnel MTU is adjusted on GRE over IPsec, but the underlay policer still drops fragments above the old profileThe logical tunnel is tuned correctly, yet the carrier-facing policy continues to enforce a smaller assumption and silently drops larger traffic.NetworkAdvanced18 minPro NETWORK-113A campus overlay fabric duplicates the anycast gateway across sites with overlapping VNIs and east-west traffic misroutes intermittentlyLocal routing works most of the time, but some flows take the wrong site path because fabric identifiers are no longer unique per domain.NetworkAdvanced19 minPro
