Hi San,
Attached is one such link that suggests that link-status traps are sent
irrespective of the qualifying arguments at the end of the snmp-server host
statement or the snmp-server enable traps statement.
Tests on my home lab indicate that your understanding is correct. But I am
a little confused as to why so many people appear to think that this is not
the case.

Simon,
According to my understanding, bgp on the host commands makes it to
send only bgp.
Can you try without "bgp" at end of host command. (I would assume then
it will send link-status, according GS archives)
