Hi,

In full mesh IBGP network(please refer diagram below), will 192.168.210.0/24 net-mask updated on BGP routing table? or will it ignor since this network is from same AS?

Thank you in advance

Woh...

Sorry, diagram looks awful. They all merged to left somehow.

Basically, each router connects to IPS via EBGP, routers and switches(layer3) are connected via IBGP.

Switch1 has 10.10.0.0/16 and 192.168.0.0/16 network, and switch2 has 192.168.210.0/24 network.

Thanks again.

If both routers and both switches are all fully meshed with eachother, the 192.168.210.0 /24 network should appear in the BGP table of all devices. However, depending on your BGP config, that network might not get installed into your IGP table and might not get advertised to your ISP(s). (no sync, etc...)

As always, I could be wrong :)
