How do I add firewalls in active and standby mode in panoroma if both active and stanby firewalls have same interface defined
. In this case ethernet1/21 and ethernet1/22
Are you encountering an issue or error message ?
There should not be an issue with adding both devices to panorama with both having the same interfaces, as this is a requirement for a HA pair
How does HA work in palo alto? Does it use vrrp? We want to use active/passive config but we want to assign different physical ips to each interface on active and passive firewall?
Regardless of the HA mode used (A/A or A/P), each firewall retains it's unique/dedicated out-of-band management IP address. The differences between the two are more apparent on the firewall/dataplane interfaces:
- The Mac/IP Addresses for the dataplane interfaces are owned by the active firewall. Nothing is present on the passive firewall (except for it's dedicated/oob management port). In the event of a failover, the Mac/IP addresses float from the previously-active unit to the new active unit.
- Is more complicated. Can be configured where no IP addressing is shared between firewalls, or can be configured with some shared addressing along with some dedicated addressing.
Generally speaking, I would recommend Active/Passive high-availability unless your network design has the possibility of asymmetric routing (ie: packet leaves firewall 1 via ISP1 and returns via ISP2 through firewall2).
Do you want each firewall to have a unique IP address just for management purposes, or is it to accomodate the network architecture north/south of the firewalls?
