HP HPE7-A07 Exam With Confidence Using Practice Dumps

In OSPF, when a router learns about an external network through both E1 and E2 advertisements, and if both have the same path cost, the router will prefer the E1 path. This is because E1 routes consider both the external cost to reach the external network and the internal cost to reach the ASBR, providing a more comprehensive metric. E2 routes only consider the external cost and ignore the internal cost to the ASBR, which could potentially lead to suboptimal routing. Therefore, the router will choose the E1 path due to its more accurate representation of the total path cost.

Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:

In Aruba gateway/AP tunnel state reporting, the following tunnel state semantics apply:

• SM_STATE_CONNECTING — indicates the AP has received tunnel configuration/keys and is attempting to bring up the tunnel; the tunnel is not yet available for client traffic.

• SM_STATE_SURVIVING — indicates the AP is in a survival/fallback condition (for example, it did not receive a fresh tunnel key and is attempting resolution via IKE); this state reflects a problem condition that can prevent successful client connectivity.

By contrast:

• SM_STATE_CONNECTED — indicates the IPsec tunnel to the endpoint is established and available.

• SM_STATE_REKEYING — indicates a rekey operation is in progress; the session is being updated, not necessarily failed.

• SM_STATE_SURVIVED — indicates the AP completed survival procedures and the IPsec tunnel is available.

Because end-users cannot connect, the problematic states are those where the tunnel is not up in normal service: SM_STATE_CONNECTING and SM_STATE_SURVIVING.

In a packet capture from an upstream switch port mirror, you would see the VLAN assignment. The port mirror captures the traffic as it is on the network, including any VLAN tags. GRE or IPsec tunnels encapsulate the original packet, including VLAN tags, but the VLAN information is not visible within the encapsulation headers.
