on a specific interface
a) you man drop received originator messages (OGMs) which does not really
reducing the traffic or
b) suspend the sending of OGMs
However, dropping or suspending should only be applied to OGMs from
non-neighboring nodes, otherwise it also affects the bidirectional link check
which would result in a confusing side-effect, marking even more packets as
In parallel it might be beneficial to configure different originator intervals
for particular interfaces. For example for a vpn connection a very large
originator interval (with a small TTL would be sufficient) since its
link-quality is not supposed to change anyway (and causing less traffic to
