They have a big brand and lots of marketing power. I've read here the juniper OS config commit process is highly valued. Though one of my coworkers who tried it in the past (as a Cisco guy) hated it.Business continuity is an important requirement of the modern network. Downtime of even a few seconds might cause disruption and inconvenience apart from affecting the OpEx and CapEx. On all Junos platforms, the Kernel Routing Table (KRT) queue can get stuck due to a memory leak triggered by interface flaps or route churn leading to RIB and PFEs getting out of sync. The memory leak causes RTNEXTHOP/route and next-hop memory pressure issue and the KRT queue will eventually get stuck with the error- 'ENOMEM -- Cannot allocate ...Problem. On Juniper Networks PTX and QFX Series devices with packet sampling configured using tunnel-observation mpls-over-udp , sampling of a malformed packet can cause the Kernel Routing Table (KRT) queue to become stuck..
