Hello Job, Im happy with that, (not that i have a say either way ;) )
I was wondering would it be worth while to add rule to limit on the aspath length that would be accepted in the examples/ bgpd.conf file also I typically reject prefixes on my ebgp routers if the prefix has an as path length > I was just wondering if you / the community think there is any value to that being added to examples ... Or am i being overly restrictive ?
