what functionality in EOS can be used to detect unidirectional links, similar to UDLD in Cisco IOS?
At a first glance I see the following possibilities:
- Loop Protect, which requires reception of BPDUs
- BFD (for routed ports (emulated using a VLAN with just one port in it) with routing protocol adjacency)
- IP SLA (for routed ports used with static routes)
