IBGP routes to EBGP question

[Bekzod Fakhriddinov]

Hi guys. Is it default bgp behavior when ibgp routes are advertised to ebgp neighbor ? (bgp sync is disabled) .

Thank you

Hi

apologies but you could provide more details about the question? the BGP router who is advertising the prefixes will be seen as the next hop for the eBGP router.

I guess i found answer , as I understand  it's normal behavior when iBGP will advertise routes from another iBGP to EBGP peer.

I saw some internal routes advertised to ebgp even i didn't have network or redistribute command under router bgp , then i started to dig in why and how (because  i don't need those routes to advertise to ebgp )
