Requesting suggestions for the following scenario, let's say we have 2 service providers (SP) offering MPLS VPNs through Option A (Back to Back VRF).
These SPs are connecting through two PE/ASBRs each, like SP As, PE_A1 and PE_A2 and SP Bs, PE_B1 and PE_B2.
PE_A1 is connected to PE_B1 and PE_A2 is connected to PE_B2, this configuration is to offer PE redundancy.
I am thinking of having HSRP between these different PEs. But reckon there has to be a better way to do this.
