ASR1002 odd layer 2 behavior

[axl8227]

I am facing an odd layer 2 behavior between 4 Cisco Router ASR1002-HX connected at the same Cisco Catalyst 2960 within the same vlan. Randomly each router can't reach the others within the same local vlan.

No layer 1 issues are present.

We face the same issue trying change L2 switch, sfp, cables, vlan, ip addresses, removing any L3 protocol and static route, clearing arp and setting static arp entries.

Updating the firmware from 16.3.3 to 16.3.6 did not solve.

Did someone ever face the same issue?
