BGP question, why do I get "Not advertised to any peer"
Below is from an isolated lab configuration, appologies to the actual
owners of any addresses of AS numbers used.
I have two routers connected together via a serial line. They are in AS400.
They are both connected to AS100 via another serial line. Both have a route
map affecting advertisements to AS100. They each have an ethernet with a
/24 on it. The /24 is getting into BGP via a network command.
The two routers have the loopbacks 6.6.6.6 and 9.9.9.9
network 100.0.0.0 /24 is connected to the ethernet of router 6.6.6.6
network 100.0.1.0 /24 is connected to the ethernet of router 9.9.9.9
When I am on router 6.6.6.6 and I look at the advertisement of network
100.0.1.0 /24 is looks fine
When i am on router 9.9.9.9 and I look at the advertisement of network
100.0.0.0 /24 it says "Not advertised to any peer"
Any ideas why the difference???? Why can't 100.0.0.0 be avertised to any
peer?
Both routers have been rebooted. The configs look almost identical.
