Support for ECMP hashing of NP7-offloaded GRE tunnels

When configuring a GRE tunnel, you can use the loopback-ecmp-offload option to support ECMP hashing for offloaded GRE tunnels over software loopback interfaces.

config system gre-tunnel

edit <tunnel-name>

set loopback-ecmp-offload {disable | enable}

end

loopback-ecmp-offload enable or disable ECMP hashing (or multi-tunnel support) for offloaded GRE tunnels.

You cannot change to the loopback-ecmp-offload setting after creating the GRE tunnel.

Example configuration

Example loopback interface configuration:

config system interface

edit loopb1

set vdom "vdom1"

set ip 10.10.10.1 255.255.255.255

set allowaccess ping https ssh snmp http telnet fgfm

set type loopback

set snmp-index 57

end

Example GRE tunnel configuration

config system gre-tunnel

edit "gre1"

set interface "lb01"

set remote-gw 10.10.10.2

set local-gw 10.10.10.1

set loopback-ecmp-offload enable

set keepalive-interval 1

end
