If the ISL between two VSX core switches is down and logs indicate that Core-2 has disabled its VSX LAG interfaces, it means Core-2 has disabled its VSX LAG interfaces, likely as a protective or failover mechanism.

Keepalive packets being dropped (Option B) may cause issues but logs specifically state interface disablement.

Both switches forwarding traffic (Option C) is unlikely if ISL is down.

Downstream switches inability to forward traffic (Option D) is a consequence, not the cause.

When configuring OSPF on a point-to-point network type (typically a direct link between two routers), OSPF treats the link as a broadcast-less point-to-point segment.

This reduces unnecessary OSPF overhead by eliminating the need for:

DR/BDR elections (which generate LSA Type 2 advertisements for broadcast multi-access networks).

Thus, changing network type to point-to-point reduces the number of LSA Type-2 advertisements, which are used to describe the network segment in multi-access environments.

No impact on number of routes (LSA Type-3 is about inter-area routes).

The default is usually broadcast or point-to-multipoint depending on interface.

When enabling ARP protection, it is best practice to wait at least a week after enabling DHCP snooping before enabling ARP protection in a live network. This allows the DHCP snooping binding table to stabilize, ensuring ARP protection has accurate IP-MAC bindings, reducing false positives.

Immediate ARP protection may cause legitimate traffic to be dropped.

Lease times and DHCP server utilization are less critical.

This staged approach minimizes disruption.

Comprehensive Detailed Explanation:

VLAN 1 is often configured as the native VLAN on interfaces to support Zero Touch Provisioning (ZTP). During ZTP, devices communicate over VLAN 1 by default to download their configuration and updates.

LLDP and UBT are unrelated to native VLAN configuration for provisioning.

MSTP relates to spanning tree but does not dictate native VLAN usage.

Thus, VLAN 1 as native VLAN facilitates ZTP processes.
