I have a EBGP problem about MPLS CE router.
My tracking system report CE router BGP is reestablished in one minute. When I check CE router logging, I can't find anything about BGP establish information. For example: Neighbor UP/DOWN.
When I use "show ip bgp neighbor X.X.X.X", I can see "last reset YY:YY:YY due to interface flap". When I check logging again, I can't find interface UP/DOWN information. "Last reset time" = "show ip bgp summary UP/DOWN time". I have no idea about this.
I don't know why? In other time, BGP neighbor or interface UP/DOWN had information in logging, but in this time not.
When I shutdown interface and clear ip bgp *, I can see log on the router wiht "show log" command.
Do you have any idea of this?
