I am currently working on a network redesign project with all Cisco gear. Our network engineer is opting for a complete HSRP Active/Active environment. According to all deployment documentation, HA Active/Passive seems to be the preferred methed for the Palo Alto's. I see that the PA's do support A/A HA using VRRP, so I do not see a configuration issue. Can someone provide the pro's and con's of deploying the PA's in an A/P vs. A/A environment? Are there any performance implications? Are there any issues when using the PA's in an A/A configuration for VPN termination, etc...?
Gotcha. Perhaps this is more what you are looking for on the Cisco side?
I'm only finding ECMP articles on PAN related to eBGP.
