If that's CRC errors which cause the OSPF across the link to flap, then You could configure a RMON event with appropriate thresholds, the OID is in the ifJnxTable: aarseniev@labrouter> show snmp mib walk ifJnxTable ascii | grep crc ifJnxInHslCrcErrors.1 = 0 ifJnxInHslCrcErrors.4 = 0 ifJnxInHslC

Hello, Not sure what exactly You are trying to achieve, looks like You want to delay announcing this link into OSPF (and by extension, using it for transit traffic) unless it has been stable for 3 secs. You could achieve this by defaulting this link to broadcast (if it is currently configured a

Dear experts, I currently have a wan link between two MXs that sometimes is experiencing errors. I’ve on top of the link OSPF (timer 1/3) as routing protocol and I’d like to find out any possible way to exclude the link when errors are in place and below to the 3 seconds of the OSPF timers. I’
