BGP prefix alert via EEM

I need to limit the amount of BGP prefixes that we send out to your ISP

This is a WAN conneection and we are limited to 50 prefixes,

To prevent us ever hitting that and risking the link going down, I want to limit the prefixes downstream.

I will be using this on the downstream router

neighbor 10.0.0.150 maximum-prefix 48 100 warning-only

My question is this will generate a syslog.

Ideally I want to fire an email directly from the router using EEM

I already run a very sucessful route-table monitor using EEM

I need something like this but to tell me about BGP prefixes only

Has anyone done anything similiar?

Thanks

Roger
