GRE Tunnel From F5 to Linux Server previous discussion https://devcentral.f5.com/questions/gre-tunnel-from-f5-to-linux-server

This is exactly what I am trying to set up but even after seeing the answers I still am not clear what the local bigip address is suppose to be, what traffic group for the self IP I need, what the self IP should be, or what this part means "Tunnel objects on BIG-IP act similarly to VLANs. The outer addresses should be configured as the Local and Remote address on the Tunnel configuration. MY_INNER_IPADDR should be configured as a self-IP - since BIG-IP doesn't have a directly analogous concept to Linux point-to-point links, as long as your IP addresses are adjacent and the lower one's last octet is a multiple of 2 you may be able to configure a /31 subnet for the self-IP to get similar behavior."

This are some real IP address for the set up not sure what to put in PEER_OUTER_IPADDR= or MY_OUTER_IPADDR=

GRE2 Linux Server (MSI):
ONBOOT=yes
DEVICE=tun0
TYPE=GRE
MY_INNER_IPADDR=10.31.61.81
PEER_INNER_IPADDR=10.31.61.82
PEER_OUTER_IPADDR=
MY_OUTER_IPADDR=10.31.61.10

GRE2 Linux Server (F5):
ONBOOT=yes
DEVICE=tun0
TYPE=GRE
MY_INNER_IPADDR=10.31.61.82
PEER_INNER_IPADDR=10.31.61.81
PEER_OUTER_IPADDR=10.31.61.10
MY_OUTER_IPADDR=
