Did you get the prefix of the locally configured loopback into bgp table

vrf oneone


address-family ipv4 unicast

  aggregate-address summary-only


it seems that if I have a loopback interface with ipv4 addr that it will not kickoff that bgp aggregate advertisement,
BUT, if I delete the loopback interface and from another router elsewhere,
inject via igp (ospf) that route for then bgp will aggregate
and send out the aggregate address summary.


Is it true that a member subnet of an aggregate address LOCALLY configured
on a loopback WILL NOT be enough to cause bgp aggregate address to kick in ?
