During a cut this weekend I wanted to aggregate our class C advertisements.
The original config was
router bgp 12345
The new config was
router bgp 12345
My reasoning was that this syntax would advertise both of our class C's. However, when the BGP session established, while I received all external routes from the upstream peer the peer received none from me. On further examination my router was not sending updates. If I returned to the original....ie not forcing a mask...it worked. So my question is, do you have to "define" the network first before either aggregating or splitting A's, B's, or C's, or is there something else I'm missing? I would also like to advertise only 3/4 of our Class B as well but had the same issues.
Ooh, that's making sense. The router has a static which points the entire class B to the next internal hop. So, is the best idea to turn off auto summary or replace those statics with *exactly* the same routes I want to advertise?
