Let's work through an example: An ospf router has interface GigabitEthernet0/0 with IP cisco address /24 and interface GigabitEthernet 0/1 with IP address /24.Bgp log-neighbor-changes is a default command.In BPG the network command actually does have the more route intuitive meaning of just 'advertise this network.4527, views 11, helpful 11, replies route 1 accepted solution, accepted Solutions 11 replies.Once we have everything configured, to see route all of our BGP route commands cisco in one place we can enter show run section bgp.Advertising BGP Routes on Cisco Routers Video route Tutorial.The way we do that is by configuring a static route going to null0.We have the /30 networks configured on our interfaces and we've also entered the static route with the /24 mask going to Null0. This means that the router is advertising them itself.

Youll learn how to null advertise routes in BGP (including the differences in the way the network statement is used and the null route trick) in this Cisco route ccna tutorial. .
If we enter show ip bgp summary, we'll see that BGP is working and everything is up, but we're not advertising any IP addresses anywhere.The Network Command Works Differently for BGP than It Does for IGPs.So in our example we would have to add separate network statements for each of the router interfaces: network mask cisco network mask network mask etc.In IGPs, the network command means: Enable the routing protocol (start sending out and listening for multicast hellos to discover peer routers and form adjacencies with them) on all interfaces that have an null IP address that falls within the specified range in the network command.Whenever a BGP neighbor goes up or down it will be logged.It is very easy to forget to include this.And lastly we have with the next hop.A network statement simply means 'advertise this network.'.Next we have the route to with the next hop.
