+# Tunnel Encapsulations
+
+Tunnel encapsulations testing is grouped based on the type of outer
+header: IPv4 or IPv6.
+
+## IPv4 Tunnels
+
+VPP is tested in the following IPv4 tunnel baseline configurations:
+
+- *ip4vxlan-l2bdbase*: VXLAN over IPv4 tunnels with L2 bridge-domain MAC
+  switching.
+- *ip4vxlan-l2xcbase*: VXLAN over IPv4 tunnels with L2 cross-connect.
+- *ip4lispip4-ip4base*: LISP over IPv4 tunnels with IPv4 routing.
+- *ip4lispip6-ip6base*: LISP over IPv4 tunnels with IPv6 routing.
+- *ip4gtpusw-ip4base*: GTPU over IPv4 tunnels with IPv4 routing.
+
+In all cases listed above low number of MAC, IPv4, IPv6 flows (253 or 254 per
+direction) is switched or routed by VPP.
+
+In addition selected IPv4 tunnels are tested at scale:
+
+- *dot1q--ip4vxlanscale-l2bd*: VXLAN over IPv4 tunnels with L2 bridge-
+  domain MAC switching, with scaled up dot1q VLANs (10, 100, 1k),
+  mapped to scaled up L2 bridge-domains (10, 100, 1k), that are in turn
+  mapped to (10, 100, 1k) VXLAN tunnels. 64.5k flows are transmitted per
+  direction.
+
+## IPv6 Tunnels
+
+VPP is tested in the following IPv6 tunnel baseline configurations:
+
+- *ip6lispip4-ip4base*: LISP over IPv4 tunnels with IPv4 routing.
+- *ip6lispip6-ip6base*: LISP over IPv4 tunnels with IPv6 routing.
+
+In all cases listed above low number of IPv4, IPv6 flows (253 or 254 per
+direction) is routed by VPP.
