[beavis daniels <beavis.daniels () gmail com>]

hi

I would to enquire about the cons/pros of running a full internet routing
table in a vrf and the potential challenges of operating it in a VPN cross
a large network that does peering and provide transit.

I not a fan to support running it in a vrf.

I am looking for a list of operational and technical challenges

specifically around
1) control plane  (route reflectors )
2) forward plane (recursive lookup issues)
3) Operational
4) DDOS
5) BCP and RFC that would break  eg "BGP-SEC does not support in todays
draft to check prefixs within the VPN"
6) Vendor specifics
