GRE TUNNELS

[motasemkhater]

Hi, I have public range /27 configured on physical interface , I want to create 2 GRE tunnels with their source ip from that range . I can configure first one source as physical ip , but can I use ip from that range as a source but not configured in any interface. Note : I can't use loopbacks as I'll lose more public IPs

if you have same ISP at both the site i think it will not be any issue but generally if you use the source IP they just need to be route able for the destination you need to contact your ISP for this.

you can configure second ip address from range as secondary physical ip and use it as source ip for second gre tunnel
