Negative impact of SNMP polling on BLT behaviour #8

Closed AlainMoretti closed 8 years ago

AlainMoretti commented 8 years ago

When IGP nodes have a huge amount of interfaces (mainly subinterfaces), most of SNMP polling tasks fail and this causes BLT to miss BGP keepalives, and peering to go up and down.

FIx to be evaluated: restrict SNMP polling to interfaces belonging to IGP only.

A new option in config file allows skipping of interfaces SNMP polling. See this commit
