In the design shown:

The BGP peering between agg-sw1 and agg-sw2 is being established using loopback interfaces as the BGP neighbor addresses (10.0.0.2 and 10.0.0.4)

When BGP peering uses loopbacks, you must configure the BGP session to originate updates from the same loopback interface that the neighbor’s address resolves to

Otherwise, the TCP session fails because:

The source IP does not match the configured neighbor remote-IP which is based on the loopback address

Aruba AOS-CX requirement:

“When configuring eBGP or iBGP neighbors using loopback interfaces, apply update-source under the IPv4 unicast address family so BGP uses the correct source interface for peering.”

In the provided configuration for interface 1/1/7, there are roles specified for different scenarios concerning authentication. When a voice client attempts to connect and the RADIUS server is unreachable, the role that is assigned is the one specified as the "critical-voice-role". In this case, the "CRITICAL_VOICE" role is configured to be assigned under such circumstances, ensuring that voice clients receive appropriate network access permissions even when the RADIUS server is not available to authenticate them.

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.
