what is represents  hold time expired

reset

down

anyone light sense to me

It means it stopped getting a response from the neighbour.  After a while it tore the session down and rebuilt it.  It came up straight away when it did this.

Hi

Could you please share your BGP configuration, any change recently? Did you change from normal BGP to address family?

If the holdtime expires the BGP peering will be down. I assuming you are using the loopbacks as update-source, right?

Please all we need is how to resolve this or if otherwise that it ain't an issue kindly let us know.

All I know is that the network is working or functioning sub optimally

Hi

Are you using loopbacks to create the iBGP, is possible to know the BGP configuration?

[francishiwe1]

The journal I am making use of to study used loopbacks to form peermate.
