FQDN(Fully Qualified Domain Name) based route

Creating static route for destination based on FQDN. The FQDN can be used as the source or destination of the PBR entry, and the PBR entry can be redistributed to advanced routing protocols. Policy‐based routing is a technique used to make routing decisions based on policies set by the network administrator. Policy‐based routing may be based on the size of the packet, the source address, the protocol of the payload, or other information available in a packet header or payload.The FQDN is added as an address object, which can then be used when configuring the policy. The FQDN object can contain both IPv4 and IPv6 hosts; the number of hosts in an FQDN object is variable. To configure an FQDN address object, select FQDN in the Type field and fill in the other fields.
