This appears to be necessary and sufficient to provide MPLS in GRE (RFC4023) support. This can be used by establishing an ipgre tunnel device and then routing MPLS over it. The following example will forward MPLS frames received with an outermost MPLS label 100 over tun1, a GRE tunnel. The forwarded packet will have the outermost MPLS LSE removed and two new LSEs added with labels 200 (outermost) and 300 (next). ip link add name tun1 type gre remote 10.0.99.193 local 10.0.99.192 ttl 225 ip link set up dev tun1 ip addr add 10.0.98.192/24 dev tun1 ip route sh echo 1 > /proc/sys/net/mpls/conf/eth0/input echo 101 > /proc/sys/net/mpls/platform_labels ip -f mpls route add 100 as 200/300 via inet 10.0.98.193 ip -f mpls route sh Also remove unnecessary braces.
