Re: dmvpn-phase-1-dual-hub-with-3000-spokes-with-ospf

Hi,

Nobody can tell you an exact number, it also depends on number of prefixes per
spoke, overall network stability, but with a proper BGP configuration you
should be able to go beyond 3000 spokes.

hi
What do you think how much one ASR 1002 with RP2 can handle bgp peers?

Hi,

Encryption performance is one scalability issue, hub needs to support the
sum of bandwidths for spokes. But in DMVPN, the routing protocol and
associated number of prefixes per spoke is the problem. You should go with
ASR-RP2 routers to match your encryption performance on the hub, BUT DON'T
use OSPF. OSPF can't scale to 3000 spokes. Use EIGRP with stub on spokes and
summary on hub or BGP with summary on hub.

Hi
Maybe someone will know which cisco router we can use as hub for
