STATIC NULL0 ROUTE
I'm working in BGP home lab, I do want to clarify that the use of static NULL 0 route.
There is loopback interfaces in two iBGP domain
172.16.64.1/24 in R1, 172.16.32.1/24 in R2 and the network between two iBGP routers is 172.16.1.0/64
When I advertise 172.16.64.0 and 172.16.32.0 into BGP, from the eBGP side can't find these networks by using show ip bgp
But after I run ip route 172.16.0.0 255.255.0.0 null 0 from iBGP side and advertise 172.16.0.0, I can find the 172.16.0.0 in eBGP side.
Please explain me the use of NULL0 static route why it need ?
Thanks in advance,[:D]
