What will be the issue if we use
rfc1918 private IP address range /31 or /30 in point-to-point link?
PMTU can be issue but what if i increase
9000 MTU on point-to-point link?
From ISP we get
/24 IP subnet and we are running
BGP on Edge router, We don't want to use NAT because our service required public IP direct on server.
Whole reason was using
/24 for host subnet and don't use any single IP from it for Point-to-Point link. My question was can i just use private IP
/30 between Router and L3 switch?
