Redundancy AND loadsharing with two HQ sites

[l.marrone]

Hi all,

I have two HQ sites (HQ1 and HQ2), with CE's advertising SAME network (i.e. 2.2.2.0/24) to their PE (single VPN).

If I would some "spoke" site use HQ1 to reach 2.2.2.0/24 and HQ2 for redundancy, AND another "spoke" site use HQ2 to reach 2.2.2.0/24 and HQ1 for redundancy:

Is it better use 2 VPN ?

How if I use only single VPN ?

Thanks in advance.

If I use iBGP multipath on all destination PE's, I'm able to load balance (per destination via CEF) to reach 2.2.2.0/24 but I want redundancy (HQ1 first and HQ2 second) for one half of sites and vice versa for second half of sites.

2 VPN's ?
