Wasn't that it made me feel safe, but I do have to worry about my
downstream customers who did exhibit the bug. As a provider, it falls
within my goals to limit damage that might occur downstream in my
customers' networks. Any time a bug in BGP that can be passed along
rears its ugly head, I take notice and see what changes I might need to
make to protect my downstream customers.
To date, I haven't seen any of them affect my routers. I have also
looked into issues with dampening, as I don't generally dampen myself,
but some of the downstream BGP routers can't handle the processor load
when things become extremely unstable.
