Advertising Networks In Bgp Pk Movie
How do I advertise routes into BGP?
There are two main methods of advertising routes into BGP – network statements and redistribution. On R2 we will use a network statement to advertise the 192.168.2.0 /24 network into BGP (note that bgp network statements use subnet masks rather than wildcard masks):
What is the use of interface in BGP?
BGP doesn’t care about interfaces, it doesn’t even look at them. When we use the network command in BGP then BGP will only look at the routing table. When it finds the network that matches the network command, it will install it in the BGP table.
How to add new networks to the BGP table?
Just use the network command to put the networks you want in the BGP table. One thing you have to be aware of is that you have to use the exact network and subnet mask for the network command. Let me give you an example: I created a loopback interface with network 11.11.11.11 /32. BGP uses the network command to advertise 11.11.11.0 /24.
What is the difference between BGP and IGP?
There’s one big difference though, the network command for BGP behaves differently. When you use any of the IGPs (RIP, OSPF or EIGRP) then the network command is used to activate the IGP on all interfaces that fall within the range of the network command. BGP doesn’t care about interfaces, it doesn’t even look at them.

How does BGP propagate networks everywhere?
This is how we propagate the networks everywhere, so everywhere knows how to route to everywhere else. The route in the network statement will only be advertised by BGP if there is an exact match in the routing table. For example, say you have a router with these IP addresses on its different interfaces:
What is the difference between IGP and BGP?
Unlike with an IGP, you cannot just advertise all of them in BGP in one go by entering “network 203.0.113.0 mask 255.255.255.0”. The networks on the router interfaces are all in its routing table as individual routes with a /30 mask. There is no route to 203.0.113.0 /24 in the routing table.
How to enable BGP on an interface in bpg?
In BPG the “network” command actually does have the more intuitive meaning of just ‘advertise this network.’ There is no ‘enabling BGP on an interface’. BGP uses targeted unicast TCP sessions to form peers based on your “neighbor” statements, it does not use multicast Hellos. So, the network command does not mean ‘turn on BGP on an interface.’

How does BGP advertise networks?
BGP uses the network statement in the configuration to identify what networks you wish to advertise from your local networks. BGP then looks in the local routing table and if it finds a network in the routing table that matches the network statement (and matches the mask also) then BGP will advertise it.
How do I advertise a BGP route on R2?
On R2 we will use a network statement to advertise the 192.168.2.0 /24 network into BGP (note that bgp network statements use subnet masks rather than wildcard masks): If we check R1’s BGP table we see that it has learned of 192.168.2.0/24 route, also that the best route is via R2, and that the path is through AS23:

What is the best route for BGP on R3?
The best route is now also in R1’s routing table (note the administrative distance of 20 for external BGP): On R3 we will redistribute connected networks so that we advertise the 192.168.3.0 /24 network into BGP: This works but is a little clumsy.
