Will this configuration work with static routing?

The configuration provided specifies the interface settings for both the Aruba Switch and the third-party switch. The configuration includes enabling the interfaces, setting descriptions, and assigning IP addresses along with subnet masks that are correct for a point-to-point link. The lack of the “routing” command on the Aruba Switch is not relevant to interface configuration for establishing a point-to-point link, as this involves simply setting up connectivity, not the routing functionality. The MTU setting mismatch is unlikely to prevent basic IP communication and can be adjusted after establishing basic connectivity. Additionally, the provided IP addresses are indeed on the same subnet, making them locally reachable to each other. Therefore, the configuration should work fine and has no issues for establishing the basic point-to-point link required for static routing.
To address unwanted UDP port 68 traffic being broadcast, the best feature to implement on an ArubaOS-CX 6300M switch would be DHCPv4-snooping. This feature helps mitigate issues related to DHCP traffic, specifically UDP port 68, by allowing the switch to monitor DHCP messages exchanged between clients and servers. This monitoring helps in preventing malicious or accidental DHCP server replies from misconfigured or rogue devices, thereby improving network performance and reducing unwanted broadcast traffic.
A valid VSX system-MAC address must be a unicast MAC address. Unicast MAC addresses have the least significant bit of the first octet set to 0, indicating that the address is not a multicast address. Additionally, a MAC address should not have all bits set to 1, as this signifies a broadcast address. Option B, AB:00:04:00:FF:00, fits these criteria, making it a valid MAC address for use as a VSX system-MAC address.
The 'blackhole' option in the 'ip route' command specifies that packets matching the destination route are silently discarded without sending an ICMP error notification to the sender. This means the switch will discard packets to the destined host without any additional notification.
