Advertising Network In Bgp Jx
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:
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 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 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 advertise the best external route to internal peers in BGP?
Configuring BGP to Advertise the Best External Route to Internal Peers In general, deployed BGP implementations do not advertise the external route with the highest local preference value to internal peers unless it is the best route.

Does BGP advertise the external route with the highest LOCAL PREFERENCE?
In general, deployed BGP implementations do not advertise the external route with the highest local preference value to internal peers unless it is the best route. Although this behavior was required by an earlier version of the BGP version 4 specification, RFC 1771,

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.
How do I advertise a network in BGP?
BGP uses the network command to advertise 11.11.11.0 /24. This network will never be placed in the BGP table since the subnet mask doesn’t match: Be aware of this. Make sure you type the exact network address and subnet mask when advertising something in BGP.
