Examples

Example-1: This example shows how to configure GRE interface feature template with interface name, interface description as variable, admin state (shutdown), tunnel source interface name, tunnel destination ip address, ip address of interface, ip mtu, tcp mss, clear dont fragment, rewrite rule, ipv4 ingress and egress access list, tracker and application.

Example-2: This example shows how to configure two GRE tunnel interfaces for primary and backup connections to zScaler SIG. It uses variables for GRE tunnel source interface and IP address and GRE tunnel destination IP. It uses a variable for shutdown for ease of operation. It uses adjusted IP MTU and TCP MSS to cater for GRE and TCP/IP headers respectively.
