Aruba Comware Advanced case studies
Aruba Comware Advanced · Put your knowledge to work in context.
The Aruba Comware Advanced exam is an independent study target for network engineers who already work with HPE/Aruba Comware-based switches and routers and want to prove depth beyond entry-level configuration. It suits candidates in enterprise, campus, and service-provider-adjacent roles who touch routing, resiliency, and security policy on Comware devices day to day. The exam spans nine areas: Comware system architecture and device management; advanced VLAN, link aggregation, and spanning tree; IP routing protocols including OSPF, BGP, IS-IS, and RIP; IP multicast and IPv6; MPLS and WAN/VPN technologies; security, ACLs, and AAA; high availability with IRF; QoS and monitoring; and troubleshooting. Routing carries the heaviest weight, so expect the deepest questions there. The Aruba Comware Advanced case studies are 5 cases and about 2,457 words.
1OSPF Neighbor Flap After IRF Merge
A two-member IRF stack (Master 1, Standby 2) runs OSPF area 0 toward an upstream router over a 2x10G BAGG. During a firmware upgrade, member 2 reboots and rejoins; immediately OSPF adjacency with the upstream router drops and re-forms every ~40 seconds.

A core switch routes VLAN 10 (10.10.10.0/24, gateway 10.10.10.1) and VLAN 20 (10.20.20.0/24, gateway 10.20.20.1). A policy-based route (PBR) on VLAN 10 interface sends traffic from 10.10.10.0/24 destined to 10.20.20.0/24 to next-hop 10.10.10.254 (a firewall).

A receiver VLAN 100 (172.16.100.0/24) on an access switch joins group 239.1.1.1. The multicast source 192.168.50.10 is behind a PE router in a different MPLS VPN.

An edge router uses a 1G uplink with 8 egress queues. Queue 7 (EF, voice) is strict-priority; queues 0-6 are WFQ.

A switch uses RADIUS for login with a local fallback user admin . RADIUS server 10.1.1.10 is configured with radius-server timeout 5 and radius-server retransmit 2 .
