BGP Conditional Advertising Question

[mameehan]

The not-exist-map feature is intended to allow networks to be conditionally advertised. The examples I have seen use the loss of a network that had been received from remote router A to trigger the start of advertising a different network to router B. I would like to do the reverse. That is, I would like the loss of a network that had been received from remote router A to trigger the end of advertisements of a different network to router B. Is it possible to use the not-exist-map and advertise map tools to accomplish this?

use the "exist-map" instead of "the non-exist-map" on the "neighbor advertise-map" statement to achieve what you want. This feature is available starting with 12.0(15)ST or 12.2(8)T and up.

Hope this help,
