Active/Passive vs. Active/Active

L0 Member

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...?

looks like each palo is marking the path to the standby hsrp peer for a vlan as ecmp preferred path. Is this an issue? What does that mean axactly?

Do you recall what had to be done with ecmp in an iBGP mesh? Was it palo alto side or Router/swtich side?

Like I said earlier, can you ditch the HSRP and have BGP peers with both 9500s?

You can read this.  It only applies to Juniper.  Page 8 - https://www.juniper.net/assets/us/en/local/pdf/whitepapers/2000565-en.pdf

HSRP is only lan side for servers and clients. Layer 3 routed ports from each 9500 to each palo, iBGP full mesh.
