While I'm sure there is an exact number, I don't know what it is. But it's a lot. It really depends on the scalability of your router.
But if I may ask - why do you ask? Are you seriously telling me that you believe you are going to have so many VPN customers that you think you will reach the vrf limit? Really? Are you sure? I don't exactly see any serious groundswell for VPN service demand from customers at this time (in fact, I see almost no demand).
IT's primarily going to be limited by memory and processing power.... Especially if you are using static routes. If you are using routing processes, there is also a limit on the number of routing processes (the pe/ce commit to eigrp fixes this for eigrp specifically, but not for other protocols).
I know that a customer VPN using OSPF for the connectivity between PE and CE belongs to one PDB within the PE, but coulu you tell me if a customer VPN using static route belongs to one PDB within the PE? If it is, two customer VPNs using static route will occupy two PDBs within the PE and will soon reach the router's limit.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
