Multiple Addresses in the same ethernet interface

L1 Bithead

Hello everyone.

 

I need to publish 2 webservers (192.168.23.10 and 192.168.23.11), both located inside my LAN (trusted zone) through 2 different public IP addresses (200.111.111.114 and 200.111.111.115). This is the configuration:

 

admin@PA-500# show network interface ethernet ethernet1/1
ethernet1/1 {
  layer3 {
    ipv6 {
      neighbor-discovery {
        router-advertisement {
          enable no;
        }
      }
    }
    ip {
      200.111.111.114/28;
      200.111.111.115/28;
    }
    interface-management-profile Ping-Only;
  }
  comment "Conectada a Level3";
  lacp {
    port-priority 32768;
  }
}

 

When I set these IP addresses in my ethernet interface ethernet1/1 and commit, I get this error:

 

 

In virtual-router default: address 200.111.111.115/28 on interface ethernet1/1 has overlapping subnet with address 200.111.111.114/28 on interface ethernet1/1.(Module: routed)
Commit failed

 

How can I set this two ip addresses on the same interface?

 

thanks in advance and best regards!

Try giving IP as follows:

 

200.111.111.114/28

200.111.111.115/32

 

However it is not required to assign ip address on interface for Destination NAT

Thank you very much, Pakumar... 

 

Problem solved!

This solution also works well when moving from another vendors VRRP solution where some clients have the actual router IP instead of the VRRP address. Adding the secondary host /32 ip address to the interface allows the incorrectly clients to work until their gateways are updated correctly.
