loopback interface as Router ID in a Cluster XL configuration

[Jose_Luis_Calle]

Hello mates!

CP recommends when configuring OSPF, set a loopback interface different from 127.0.0.1 ... If we have a ClusterXL, we can set the same @ip in a new loopback interface on both firewalls and set this ip as Router ID or we must maintain the default configuration? Thanks in advance!
