Priority changes DR election eligibility; peers on a link still require compatible area identifiers.

MTU mismatches can affect adjacency progression, but do not resolve a fundamental area mismatch in Hello parameters.

OSPF process IDs are locally significant, while the area of the shared link must agree.

Duplicated router IDs prevent distinct neighbors from being identified and do not address database-description MTU fields.

Interface priority affects broadcast DR elections but not the database-description packet MTU mismatch on a point-to-point link.

Suppressing Hello packets prevents adjacency entirely instead of repairing the exchange-stage problem.

Process IDs are local; different routers must still have unique OSPF router IDs for correct operation.

Timers can affect adjacency, but cannot distinguish two routers advertising one router ID.

That perpetuates the identity collision; assign unique IDs and apply a controlled process reset as necessary.

On a multiaccess segment, DROTHERs ordinarily reach Full adjacency with DR/BDR but can remain 2-WAY with each other.

OSPF DR election is not preemptive and full adjacency between every DROTHER pair is not required.

Their Hello exchange reaches two-way, and this is expected behavior on the stated healthy broadcast network.

OSPFv2 uses IP protocol number 89 directly, not TCP port 89; a TCP service permit would not carry the OSPF Hellos.

OSPF control packets are not UDP, so a UDP port permit cannot fix blocking of IP protocol 89.

ICMP ping success is already proven and does not imply that OSPF protocol-89 packets are permitted.

Database Description packets summarize LSDB contents during adjacency exchange rather than serving as periodic Hello discovery.

LSUs flood topology changes/LSAs and do not replace periodic Hello parameter discovery.

LSAck confirms received LSAs; the Hello packet carries neighbor formation parameters such as area and timers.

Static routes can help upstream redundancy but do not supply a shared stable host default-gateway address across both routers.

This does not provide one resilient virtual next-hop address and relies on client behavior beyond the requested standard gateway.

Duplicate ordinary interface IPs can cause ARP conflict and do not implement a coordinated virtual gateway role.

The standby is prepared to take over, but the active member presently forwards on behalf of the group virtual gateway.

HSRP Hello reception does not by itself identify the current active forwarding member; its state does.

The active role is established by HSRP election/priority behavior, not simply the larger physical interface IP.

Listening routers may track Hellos but are not the specifically elected standby member described as the next failover peer.

A healthy single group ordinarily has one Active and one Standby rather than simultaneous active forwarding identities.

Speak participates in election, but the elected backup role to Active is Standby.

Tracking the unchanged LAN link does not lower the active router priority when its upstream WAN path is lost.

Raising priority makes a failed-upstream router more likely to remain active, contrary to the required failover behavior.

Removing the redundancy protocol prevents the healthy router from providing the shared gateway role.

If that router fails, its physical IP may stop responding and the host cannot rely on the other FHRP member to own it.

That merely moves the single point of gateway failure to the second router instead of using the FHRP identity.

Client implementations vary and two physical next hops do not offer the one stable FHRP virtual-IP default gateway described.
