Well, if the router CAN run BGP, the feed from Cymru is only about 84 prefixes - not a lot of memory tied up there, is there?
I am *not* talking about the leaf - rather the core. I am curious what resources are needed to manage 200K BGP peers other than 200K IP addresses. Is there an IOS limit on the number of BGP peers? Memory? -Hank
If the router isn't capable of BGP, someone earlier today was kind enough to post a script that they use to find changes to one of the BOGON lists and suggested an Expect script to automatically update their router. Probably a little advanced for most leaf sites, but for someone who's responsible for a larger network -- doesn't seem that bad.
